Yeah I think it’s safe to say that Bmw is sandbagging about there claimed 445 crank hp on the 50i. I have dynoed many of my cars and know by there wheel hp is in line with the crank hp, but no way a car making 445 crank hp that’s awd and auto tranny going to put down 400 whp and the fact that this 5300 lb suv moves the way it does, something just doesn’t add up.

It wasn't top 3 priority, but it was up there. This is the family car after all. I don't ever remember gunning the car it replaced ('15 pathfinder). Honestly this car stock is impressive to me... The V8 thing was a want. My wife couldn't care less and I'm happy with the decision... (but I am still googling the X50s and realizing I could have had one for like 3-4k more lol)

I had 1997 Trans Am with a STS turbo (hence the name "ta"seal). It was one of those rear turbo setups. The engine was a forged 355... I don't remember what I was pushing, but I do remember getting a 10.9x on the track. It had a meth injection kit (used windshield water tank as reservoir), and low boost was 3-5 psi and high was 12-14psi or something. I think it was a T04 turbo. |

See I also want that MPE as well, but it seems I will need to get the square tips along with the MPE... this is going to cost me too much. I have to remind myself that this is for my wife and not me. I have my own toy already, and I'm already looking to get a used convertible 4 next year to replace my everyday car ('17 malibu) lol

Does anybody know why I can't find any info on my BPC tune any more? The guys who I bought it from & who helped build the coding file no longer reply to my email.

I don't have the answer, but they are pretty active posters on Facebook. Perhaps you could try contacting them there?

Just go BM3, everybody seems to like it and price wise it’s less then most for a flash tune.

https://f15.bimmerpost.com/forums/sh...1665231&page=2 discussing the risks associated with too much torque but I didn't want to jack that thread to continue the topic. Do you think Flash tunes put us at risk for these failures? |

Pushing something harder is always going to put more stress on it. Pounding a 16d framing nail is harder on a hammer than driving a tack. The question is, with our tunes are we using 60% of the maximum safe power capacity? Or 90%? Or 98%? It's unknown. We could start a GoFundMe campaign to raise a bunch of $ to buy 100 N63TU motors, then flash tunes on them and torture them 'til they blew, to see how long they lasted. Short of that, I don't think we'll ever really know. I love the huge power mine makes, and I'm willing to roll the dice on durability and my warranty coverage. Each of us has to decide this for him or herself.

That's really good 0-60! What tune? What's your 1/4 mile? There are dozens of n63tu and s63tu that are dead due to bent rods. Almost every tuner by now knows that n63tu/s63tu torque limit when rods start to bent is close to 700. There is actually plenty of info available for those who is interested in builds and tunes. I was a frequent *********** forum member, a lot of info there, and many tuners and enthusiasts do have first hand experience with n63tu/s63tu, including "blown" engines, various builds, testing the limits etc. If I have to guess, on Stage 1 tune you are already past safe limits, let alone Stage1+ or Stage 2. |

I'm definitely in the minority here, lol, but does anyone know of anything for the N20 on the xDrive40e? I appreciate the fuel economy but wouldn't mind a little extra oomph when I'm using gas.

I would just go piggyback route for 40e, will give you a bit of boost and IMHO is less detectable for warranty reasons. Shop around, there are plenty of sellers willing to take money, including some members on this forum who are basically vendors.
