I agree with Poppa Smurf. I also didnt know that Greddy was making 16g's...oh well. Tuning tool, clutch, gauges(boost/EGT), Straight pipe or high flow cat, Maybe a GM MAF set-up. Is this going on a FWD or AWD? But like Poppa Smurf said look into some other shops for better deals on shops. Greddy is a waste in my opinion. Look into Slowboy, AGP, AMS, ProStreet... I bought alot of parts from Kevin at AGP and Mike at Slowboy. Excellent service and good prices. Later,
