I know a lot of you guys have experience with these so if you have a few minutes to answer it would greatly be appreciated.
First upgrade should be the CAI, Cold Air Intake. This is a simple mod to do that has about the biggest HP increase of any mod available to date. I'd recommend the Sprint Booster next if it wasn't done first. The next biggest power booster is the Pulley. The 178mm should give about 25 HP increase and the 181mm 30 HP. The big 185mm should be good for about 35 HP to the wheels. The H/E and IC Pump upgrade will help keep the intercooler temps from rising out of control and causing the ECU to retrard the timing and pull boost. Plugs and Wires might help everything run just a bit smoother, but HP increases are still undetermined. The Tune: IMHO I don't think the money spent on a tune is worth the money they are asking. I wouldn't recommend any tune other than the lowest priced ones that are currently available, InMotion or SpeedInnovation. In the coming months I think more and better ECU tunes will be available. The Schrick Cams will provide some HP increase, but at about $1800 or so for a set and then maybe 6 hours of shop labor to install them, they are the biggest dollar mod available. HP gain, maybe 10-15. Dyno's are to scarce to be accurate.

Ben, there are hours of reading on here about what to expect with each mod, and everyone has an opinion. I went the easiest route I could and still keeping the car looking stock. Everything on the list above will make HP or improve performance, and that is what you are after. The numbers to me, don't mean anything. I have raced bigger numbers and won...so, to me, it doesn't matter, but your setup matters...you have to be able to put the HP to wheels, then to the track...if you do that, then you will do well....good luck with your modding, but again, you can't go wrong with any of those mods mentioned...but if you need a number to the wheels...after all that...probably in the 370 area...
