how been done remap on stock computer ant what bhp did you get max? Today I been talking with Steve from FCtuning and he said that I need aftermarket ECU to run what I want.

 

at the moment I got 370-380bhp at 1.2bat with stock injectors and stock intercoolers. I want to put over 430bhp after I put 555cc injectors and bigger IC but Steve said that I can't run that power on stock ECU I need aftermarket one.

Is it true ? I am always was thinking that stock ECU is ok for 420bhp.

437 on standard injectors tubs and coolers .....does this guy also walk on water and feed the 5000 on his days off ??? that is a serioulsy high level of power for a stock zed engine

im only expecting that at the wheels from an engine build that has cost nigh on 10 grand and using an AEM
