jb4 map 0 135i n55

[shanoo]

i recently installed got my jb4 on my car.( bmw 135i n55 with ppk )

the only mod on the car is jb hence i can only run map 1

when i use map 1 the car runs strong and fine, but when i select map 0 which is supposed to be stock the car feels weaker than it was without the jb4

the issue only occurs in 1st gear

the turbo only really starts pulling at 3700rpm, i dont know if its that ive gotten use to map 1 or the car really is weaker

when i put the jb4 into map it feels faster than map 0 boost hits earlier aswell

anyone experince any similar issues or know what could be wrong ?


going to get my jb4 off tom and see if theres a difference

Run a log on map 1 and map 4.

Then one can see if there is a problem.
