Stage 2 with DSP going crazy

[Krazyrdr83]

Ok, I'm posting this for a friend of mine. I went with him to do some pulls/logs...and this is what happened.

We did two pulls, both pulls were exactly the same. Starting in 3rd gear in both pulls, a/f jump up to 12.5 and stay above 12. Starts to knock like crazy, and rises as the rpm's rise. Once in 4th, everything settles down. A/f's drop down to high 10's low 11's, no knock, and the car really moves then. Boost, his gauge says 20 drops to 15 to redline.

Any ideas on why this is going on? Mods are full stage 2 w/o toys, 3" downpipe (catless), mopar exhaust, AGP wga off pcm controlled boost, cold air intake, fuel pump rewire, i believe that's it.

Try adding fuel in the lean ranges.. Should be able to handle the 20 spike on the car as I have stg 2 injectors and my afs are 12.0s.

ok...but why only in 3rd? in 4th it doesn't act up

because you probably have the COT (catalyst over temp) still turned on for the car. This dumps fuel to protect the cat and it usually starts in 4th gear. Thats why your afrs are 10s in 4th. add some fuel in the lean ranges and see what happens.
