I had my S2 on rolling road to day.. BUT i showes that I is running lean after 4100 RPM.. in fact after 4100 rpm it running like shite

the spec is:

1600cc std wit
turbosystem 195 chip
piper 285t2
mongoose
K&N
-34
GRS

its running bout 1,2bar i boost.. and I've turned it up to 3.5% i CO.. is this enougf??


can the std MFI deal wit this spec and boost... or is something wrong.. cause it was just when the engine really needed the fuel and the boost was high, that it under fueled it??

I going to fit MF2 very soon

by the way.. the car had 163bhp.. and it had i at 4100rpm... and i still had it a 6300rpm... so something is obviosly wrong
