I have to second this. Junior's race gas stock turbo EWG cars make +/- 5whp compared to my car. I tried helper springs and a CAI also. Didnt make 1 more whp or hold boost any longer up top.
Juan, if you dont have them already, get the GT spec or maddad exhaust manifold (EL). The only real whp adder is the tbe and the tune. The manifold will stretch your power band out to the right a little more. When i added mine i lost 10 peak whp @ like 5k, but held 15whp more @ 7200.
Obviously people will critisize this with dyno numbers, but to me, dyno #'s mean nothing.
