Truck lays over on top end?

[93stang]

I have a 99 F250 with DIY intake 4" down pipe with 5" straight pipe and super chips flash pak hand held. The truck seems to be laying over at higher RPMs and sounds like it is spark knocking, only sound I can relate it to. Any ideas?

I know the hand held is junk and I need a custom tune!!

Have you done a Wastegate Delete? Mine sounds like that when I plug the red line.

Where in NC are you? Maybe you can hook up with some of the CPA members and lets us see what you mean? Hard to diagnose by typing about it.

No have not done the waste gate delete, will have to search that!

I live in Pikeville, about 60 miles East of Raliegh.

Waste Gate Delete is simply taking the redline off of the waste gate and sticking it on one of the boot clamps to plug it. Made mine sound weird. Thot maybe you had done that?

Check out the CPA. We would love to have you join!

Mine red line is in stock postition which is plugged to the waste gate. This is easy to be misunderstood. I consider it "plugged" if you put it on a bolt head, etc.

Mine made too much racket when I took it off of the waste gate and plugged it so I put it back stock.

Make sense?
