1st, let me say thanks for reading my post. I have a X4 M40i G02. Love the car, but want more from it. For starters, I will say I learned first hand "to play you will pay." Since 20K miles I have had a VRSF down pipe, MHD Stage 2 OTS and XHP stage 2. At 48K my engine seized due to the oil pump failing. Never had any issues with the car. BMW said I voided my warranty with the catted DP and tune. So yeah, I ate the bullet of replacing the engine. Since replacing the engine, i'm invested in this car till the wheels fall off. This is my daily driver.

I have decided to upgrade to DAW ultra flow X turbo and a custom tune, but only on 91oct. Here is where your advice would be appreciated.
1. Tuners - SubPar tunning or HTE performance?
2. Is a cold air intake necessary? (I hear only for the sound) considering MST intake based on post here.
3. Is a Mid pipe exhaust necessary? (considering: https://trucranemotorsports.com/prod...caAlqtEALw_wcB)
3a. Or should I get full exhaust?
4. Any other mods you suggest?

Thanks for your time.

Sorry to hear about replacing the motor.

I have a 2020 x4 m40i - Full SuperSprint Exhaust, Evo DP, BM3 Stage 2 93 AGGR tune, xHP Stage 3. Love the torque and the sound. I also Auto-x and will eventually get to a track.

Next step for me is a Hybrid turbo and custom tune.

A full exhaust would be nice with that DAW Flow X!!!

How do you like your SuperSprint Exhaust? Worth the money? Also, what is "Auto-X"?

Exhaust set me back $5k, but quality, sound and performance are great!

Auto-X - Autocross racing. Parking lot race course against the clock. Short burst to 60mph and a series of turns and braking. It's fun and my car keeps close times to m3s and m4s.

Was this a used motor?

Nice. Since i'm staying on pump gas, the owner of my turbo company and tuner both told me to stick w/ the mid pipe. Apparently I will get get great sound from intake, turbo and mid pipe.

Sorry to hear on the engine, Is that a common occurrence? Were there any hints something was off before hand?

Not that I know of. As mentioned. I never had any issues with it prior.
