well i finally took the plunge and ordered the KO4's, inlet pipes, piggies pipes and a borla cat back. the only real concern i have with the setup is my ecu, im currently running the GIAC program. the folks at VAST said my car would run but probably not perfectly. i want to get a tune from them but the funds are running low. should i try and trade my ecu with the GIAC chip for a stock ecu and some $$$ and data log my ecu once i get some money so they can set me up with a custom tune or just run my ecu and hope for the best? does anybody have a similar setup? and how is it working for you?

 

just run the GIAC untill you can afford a tune

 

^^ yup, wont be as good as the 3- tune, so save up for a new clutch and fueling for stage 3. oh and labor too! $$
