1997 supercharged cobra/problems
 

We finished installing a 7psi kenne bell kit on my friends 97 cobra. its very easy and pretty much bolt on. The car started fine and runs well. In the third and fourth at part throttle there is a one second lag and sometimes the car backfires. Anybody have any opinions ???

1997 cobra, longtubes, x-pipe, no cats, 4.10 gears, twin 65 throttle body, mac cold air, ngk tr6 plugs, boost-a-pump set at 25%,


thanks

Are you using the chip from kenne bell.

RE: 1997 supercharged cobra/problems
 

Yes,and we followed all the instructions. we didn't change anything.

I think you have your boost a pump set to high it should be around 10% with only 7 psi. You technically dont even need to have boost a pump on till u run about 9psi. I have mine going just in case. Do you have an air fuel ratio guage in the car. If so whats it reading at.

Thanks, I'm going to try that and recheck the plugs at the same time. They are new, but you never know.

Thanks
