Chris get an N55 or N54? I'll have to check on FB tonight. Hopefully an N55 as basically everything BMW can have one in it! They just cracked the boost control on the electric wastegate newer ones and have over 400whp with minimal mods on stock turbo (this was a 435i).

I was hoping to get mods on last weekend, but I got that stomach bug that went around. Hoping for this weekend to at least get the tune on it.

Can't tell from the outside, but it isn't an early N54. It is 2009-2011. Only the 2011 was N55, but everything since 2011 is basically all N55 for every BMW from the 1 series all the way to the 7 series, including the SUV's. The N55 is also more reliable and more efficient.

Alpina TCU flash completed, no more lazy shifts in Drive, and its nice to see what gear its in Drive mode. Thanks JET for suggesting the update.
Couple things I have left to figure out, summer tires and getting the transmission fluid changed to redline d4 along with a new filter.

No problem. You mean better shifts in S mode? D on the alpina bugs a lot of people as it is in 6th gear by 40. How do you like D? I haven't done it yet because of that.

Ditch the run flats when you get summers. Loving my pilot supersports, but mine are RFT. Going to do same tire next time, but no RFT.

I like the way D is working. The car has enough torque that the shift to 6th @ 40 doesn't bother me. It gets better mpg now that it isn't wearing the crap out of the clutches.

LOL.

So, I got my tune in today and took it for a spin. I was just on Map 1 which is 12.5psi vs stock at ~9psi. Holy shit! Felt like I added 2 more cylinders. I can't wait to get my flex fuel wires on and toss E40 at it. Then it can run 16psi. Very excited to go play with it some more!
