Another supercharger pulley question... sorry

[Matt_Chedzey]

Hi guys, i know theres loadza posts about supercharger pullys out there but i just wanted to get things straight.

|'ve read ppl say that : -

15% requires no ecu remap
17% may require a remap
19% defo requires remap and maybe other things

I have an AC Schnitzer tuned 2003 model and just wondered if anyone knew anything about the level of mods these cars have. I believe it has been remapped by Schnitzer, so does that mean it will be better off going for the 17% reduced?

Any help will be appreciated, thanks

I don't think that 15%, 17% or 19% by themselves require remaps. Most people running a 19% reduction pulley also add larger injectors, which necessitate a remap.
