C32 engine trouble
basically, I have a Crossfire SRT6, which you probably know is a reskinne slk 32. I attached a Code3 performance supercharger pulley, and I'm losing power on the dyno. Around 10 hp. My understanding is that this shouldn't be technically possible, except in two ways:
Belt slip,
or computer problems.
How do I determine if it's slippage? I'm not hearing anything...
As for the computer, does anyone here think that the Australian model may be computer detuned, so that the extra boost made by the pulley is causing the ECU to 'panic' and limit the revs? Any help welcome!!!
