We still haven't had any stock X3M or X4M 1/4 mile times shared in the Qtr Mile thread, so if you get a chance to run stock before you tune, it would be helpful for the community's reference databank. No one really knows what the 30HP difference in base and competition models makes at the Strip (at least I haven't seen any formal slips in that regard).

You can try the 93 tune but make sure you only use best quality 93 gas (Shell or similar) and definitely get some logs to see if you get knocks. If you do, switch to 91 tune (this is what PTF will tell you).

Bjs, wawa, giant, costco, etc source their fuel differently based on location. Luckily my two local bjs gas stations are really good. Which are the cheapest in my area.

No way I'm spending an extra $22 per fill up lol I would much rather travel to the nearest e85 station. And fill up like an 8 gallon container and store that.

I think I'm going to grab a tune from MP in late spring next year. Probably go with the 91oct 570whp tune. I have access to 93 nearly all the time but occasionally I go places where I can only get 91.

This might be a bit off-topic and probably has been asked before; will the horsepower increase be higher on a x3mc vs x3m?
So hypothetically both cars with the same tune, will the x3mc always make more horsepower? |

^he would know better than me but I agree. Hardware is same and you're overwriting so target boost should be same. Comp is just 1.5 psi more than base.

I went with Racechip. Racechip uses a separate module installed under the hood with quick release disconnect so you can remove the module when you go in for servicing. that way the dealer doesnt know you have a tune and everything is stock when you are there.
Also if they ever had to do a update flash on the car you wont lose your tune. Racechip also has a smartphone app for choosing different settings on the tune. |

Yes, it is.
The harness comes with bypass plug or dummy plug where it plugged in to the harness when the module is removed. So the car is back to stock when it is used. The harness is OEM look, so it blends in well with the factory harness.

Sorry for the redundancy in my question, in case that something went wrong; how does Race chips warranty work? And what happens if the dealer realizes the car is modded?

I don't remember the whole details, it is a long page to read. If dealer realizes that the car has been modded, there are many many different scenario. All depending on the situation and dealer reps.
