after a little bit of work on my car, i would like to overdrive the charger but not blow the HGs again. exhaust would be the SCP 2.5-3-2.5 setup, with gutted cats. blower will be a MP2 with highflow plenum. i will have some other intake mods on the car as well. will a 5% on the MP2 be too much, even with the aftermarket exhaust? another thing, does a intercooler fan really help drop 1/4 times? any praises or complaints? thanks
