BMS N55 Stage 1 question

135iNreag · 06-19-2011, 08:08 PM

Hey everyone I had my JB3 installed yesterday for my N55 and the car feels great....pulls harder, driveability is great etc....However my car is a 6mt and it seems like whenever I go full throttle in first and then shift to second the car doesn't pull that hard almost a bogging type feel this is with dtc all the way off. I'm not sure if this is my mind playing tricks on me or if something is holding it back. If I do a roll on in 2nd the car is fine through every gear. Just starting in first and shifting hard to second the car feels like it's losing power in second. Has anyone else noticed this?? It felt much better today when I tried it a few times but still felt something was off. Wondering if the car is just adapting, etc...let me know your feedback on this everyone!

What rpm do you shift at? I think you're supposed to shift at 6k. Also if you want an exact answer, do some logs and then email them to Terry so he can check them out.

I usually shift around 6000-6200 ill do some datalogs and see if anything is abnormal. Oil temps were normal at 240.
