I'll be honest. It kind of annoys the hell out of me that the X3 M40i didn't release with the B58 at 380HP like the upcoming M340i. What is BMW afraid of? Its not like the X3 M40i would be faster than the M340i. Why just jump out in front when you could rocket forward?

well...it is an SAV to begin with. and also, they're probably wanting to make the X3M a very big difference than the m40i performance wise. might give a clue on to how much hp the x3m will be...definitely over 400...

I think the m40i is actually a perfectly tuned sav. I don't want more power in this, it has great mileage, it's comfortable, it's not loud, it sounds wonderful, and it's the perfect height and width. I can't use all 355hp often enough to justify even more than that...I wouldn't reject more power if it fell into my lap, but I don't feel like I'm lacking the extra 25+ lol...

So what if it's an SAV? The incoming X5M will be getting 600+HP. The X3M will be 100X better than the M40i and it won't be just about "more power". There are too many differences to list as to why the X3M will be better. Adding 25 hp to the M40i won't hurt the X3M lol. It's going to be a big difference...regardless.

I don't care about mileage. I want more power and sound. Maybe the 30i would have suited you better. The SAV cargo/performance/hp wars has a lot to do with the competition. I dislike how BMW squeaks forward versus the competition only to get passed. That 25HP you can't use or feel would make the M40i the clear segment leader and I think BMW could move forward without constantly handicapping themselves. IMO, it is silly how BMW plays games with performance figures in every segment. Let's not hurt the outgoing X5 50i's feelings and keep it at 355HP lol. There were people who swore the M40i would never get more than 330HP. Remember those threads/posts?

You may not want more power but I bet you are in the minority in this thread. A 380HP X3 M40i or a 480HP X3M is not for you and that's OK.

I just want to say that who cares what strategy they take? add a 500$ chip and get 60 to 80 more hp.... unless I line up next to a glc63 amg , trackhawk or quadrafuligligligo I'll be coming out on top and at 30k$ less

[SSIMPS]

I just finished installing my JB4 and it is incredible. This is my third BMW that I've had a JB4 on, and it never ceases to amaze me.

One thing I wanted to note is that the B58 JB4 is incredibly easy to install. Especially compared to the N54 or S55. The TMAP and MAP sensors are incredibly easy to access, the cowling and engine cover pop on/off without any tools, and access through the firewall to the OBDII port is only covered with a sticker and not a thick rubber grommet any more.

Literally the ONLY tool you need to use is a 10mm wrench to disconnect connector from the negative terminal on the battery. Overall the entire process took less than 1 hr and my guess is that next time I could complete it in 15-20 minutes. I used to fight with M4 for hours trying to get my hands at some of the connectors.

This car was quick before, now its a MONSTER

If anyone is in Southern CA and either wants to see what the car feels like, or needs help with an install I am happy to help. Just shoot me a PM

lol, actually maybe the m40i isn't for YOU.

go get the x5m or wait for the x3m then or go sell your m40i and get a jeep srt8 if all you're after is power and sound. bmw has a lot more to offer than power and sound. you went with wrong vehicle so maybe that's why you're feeling the way you are...

and no, the 30i wouldn't have suited me better, I got what I did because the 30i wasn't enough power for me, but the m40i is PLENTY. it's a great balanced vehicle. sorry I'm not sorry you're feeling buyers remorse...it is an unsettling feeling.

to each his own...

right. I don't see any point of crying over 25 hp when tunes are readily available.

The Macan GTS and GLC AMG43 may beat us off the line. The extra 25HP would have ensured that they couldn't....stock with no tune. I am referring to SAVs in this class and approximate price bracket only. The other vehicles you mentioned are in X3M or X5M territory. For once I'd like to see BMW not hold back and bring it. They did a great job with the M5 vs the E63. That strategy should work across the line.

You're right. X3M CP is for me

You can ride around in your M40i in Eco-Pro mode. It's nice and quiet and gets incredible gas mileage. After all...it's just an SAV.

The X5M and Trackhawk are in a completely different class. Almost pulled the trigger on a X5M but couldn't justify the size. It is just too big for my needs. Maybe one day because the X5M is truley remarkable. Looked at a Macan Turbo but it's too small. X3 M40i fits the temporary void until 2020/21 for the X3M/X4M CP.

I lease a new vehicle every 2-4 years so buyer's remorse doesn't apply to me. Neither do non-warranty tunes. X3 M40i is a great SAV but it IMO, it is still under powered. You can look at the upcoming Macan GTS and offerings from other manufactures to see that it is. Newer offerings from the competition are "always" better but BMW won't make that mistake with the M340i (maybe even with the Z4 M40i). It is going to be appropriately powered for its class at 380HP and 25HP more than its C43 competitor until 2021. No reason BMW couldn't do the same with the X3 M40i. The extra 25HP would have made a big difference vs the competition.

My initial post had nothing to do with whether or not it has plenty of power for you. It wasn't a stab at the M40i but at BMW for holding back...which IMO, they did. Enjoy your M40i...I will.

Ill come back to you with my 0-60 times when summer tires are back on. 3 weeks

but I can guarantee you no GLC43 or Macan gts will beat me if they are stock

I'm pretty sure I'm putting down 420hp and 460 torque with a 0-60 probably around 4.2 secs

Unfortunately, with my small winter wheels, my tires are smoking all the way to 30-40km/h on dry pavement (launch control is a hell of a thing)

FSociety is already getting almost 4.0s flat in his modded X4 M40i. You should break 4 seconds. I am talking about stock vs stock. Modding anything to beat the competition is a different sport. The M40i should of came from the factory with 380HP+ via upcoming M340i.

At this point id do small bolt on things like air intake, but id avoid going to something more complicated like meth injection ... Im not sure what my next step is

I'll drive around in the m40i in any mode with no regrets buying it lol. have a hard time believing the "size" issue was what was holding you back from the x5m....you sure it wasn't the $100K+ sticker and the $50k difference between the two vehicles? the size dimensions on the wheel base are less than 3 inches, the length overall is 5 inches difference, and the height is 3 inches........ hardly a size competition between the two. buyers remorse is valid either lease or a purchase. you're stuck with it unless you want to take a bath. but okay.

and again, that is your opinion that the competition is "always" better...a macan GTS rolling in at 19K (what another forum member stated he paid for it above his m40i) is NOT ALWAYS BETTER at a staggering $20,000 price tag increase...lol. it's not. it's about perception of what you're getting and what you want in a vehicle. your perception of what you were getting into versus what it actually is was so different it made you regret SOME (maybe not all) parts of the purchase otherwise you wouldn't be so pissed at bmw for whatever you think they didn't include in this perfect sav...

anyway...

we'll be anxious to see you x3m when it comes out!

Awesome!! As soon as the winter stops coming back I'm going to get this done! I'll try map3 with petro 94! Hope to get a little over 400hp! Also can't wait to time the car on the 1/4 mile!

Nope, no regrets. Nope, it wasn't the $100K+. I like the nice personal attack here where you assume / imply I can't afford it. I am not going down that road with you lol.

Comparing the size of the X5 vs the X3 and saying "hardly a size competition between the two" is laughable. I am not going down that road with you lol.

I disagree. The current GTS is a better overall performance SAV despite the price difference which could vary from $75K to $100K+. Again, the M40i should have had more power from the factory and is far from perfect. You are entitled to your opinion and I mine.

I will be getting into a X3M/CP in 2021. Or maybe a FPace SVR. I will see when the time comes. Maybe you will be around. Maybe you wont. Maybe I won't. Regardless, I won't be looking for you lol.

Take this bullshit somewhere else. No one wants this to turn into the Evo/STI forums circa 2010.

Both of you are entitled to your opinions, but let's try to keep these threads on topic.
