I have an 08 tc and have a k&n typhoon intake and forge bpv. Once I get my taxes and next check I was going to buy my next mod.. I'm torn between gm stage 1 or the Zzp intercooler package.. I'm not sure if I want to upgrade my turbo so I would order it with the block off plate and flange.. it's going to be 900 with shippingand the gm stage 1 is 510 at ced.com. there are a lot of pros and cons about getting each one.. I have jury duty on the tenth of march and ironically that's when my car payment is due. So I may have to pay it early.. but I don't know if I should just get the more expensive one out of the way.. what would you guys do? If I bought the Zzp, I'll have Alittle over 100 left which is doable.
