I just modified my X5 50i: velos Tuning , they just figured out the software for the stage 2 tune. First 50i to be tuned in the U.S. it gave me 154 extra HP and 100ftlbs. Took it to dyno today. I'm sure they have something for the 40i, or can developers it quick due to just finishing mine for the 50i. |
do you have the Dyno chart (full one) that's cool, I assume it was a ECU flash? No one by me has tuned them yet from what I've been told It looks like you're pushing 5psi more boost than stock which is 15psi
Can I see the stock Dyno too? normally BMWs are making more WHP than they should but if it's only truly making 387whp I'll be a little disappointed
Post some videos too! What's your 0-60 look like now?
