just installed a HSR on my stock 350
Ok just in stalled a HSR on my stock 350.Since i installed the intake the car is lazy and has a higher idle.I checked for Vac leaks and so far i cant find any.I played with timing and set the timming to where i got the throttle respones.FPR that came with the setup is not adjustable.Anyone have anything to add to maybe why this setup is not running so good? Thanks

Did you set the timing with a timing light?

Whats your scantool say? IAC counts high/low?

What fuel pressure are you at?

Its a tunnel ram and not a TPI, it will feel different down low I expect.

How about fuel pressure?

Did you hook all the vacuum lines up right? How are you checking for a vacuum leak? Carb clean, propane torch?

If your IAC count is at 0, you have a vacuum leak.

Does it stumble or does it just not seem to have the power the TPI had?

I went back and checked my tps which was out of wack.After i adjusted that i retimed the engine and found that one of the Vac lines must have fell off on the back of the intake.I have to wait till i get a new fuel press gauge to check my fuel psi.The car has power now like it had before with the tpi? Now The engine pings a bit, must be lean?
