Re: Tune-port install

Your problem with falling off at the top is caused by the intake. If you want to solve that problem get an aftermarket TPI intake.
I had a TPI on one of my trucks, and the truth is, I didn't drive it at high RPM's so the lower end power is what I really wanted, and that is what the stock TPI provides.
