I'm trying to figure this out before I do the head cam and intake tomorrow. From a dead stop, if a go 3/4 throttle all the way the car will pull smooth all the way to 5750 RPM (that's the farthest I've taken it). And if I go full throttle from a dead stop it will pull hard to about 4200 RPM and then sometimes it will act like it's got a dead spot between there and 5500. This doesnt happen every time but it does sometimes and it pisses me off.

The ignition is all new Accel, so I know thats not the problem. My guess is timing or running to rich or to lean. I did the AFPR a while back but I only have it a little above the halfway point.

Any help would be greatly appreciated!


Thanks

 

The power enrichment mode (WOT) on the stock chip really cuts the fuel down above 4k and may be causing you to run lean during WOT on a car with improved exhaust and breathes well.
