Got a problem, don't know what its related to.... I'm guessing either fuel or ignition. This seems to happen in 1st gear only.

When I floor it, once the rpms go over 5k I'd say it sounds like the car is misfiring like CRAZY, like RAPAPAPRA, really rapidly, the rpm continue to rise, but the "pull" just doesn't seem to be there... now every other gear seems to be just fine...
Thought it was my spark plugs, so i swapped those out today for some brand new E7s gapped to .28, but I still have the problem..
Link detects no knock or misfire... :confused:
 
Check your fuel pressure, could your tune have been change or messed up on dsm link?

Fuel pressure reads 40psi with vac line hooked up. Nothing really seemed to change with link, I have been messing around with the airflow to get my LTFT Lo+Mid normal, but that's about it.
 
Watch under the hood in the dark, while someone revs engine, for spark jumping to ground from spark wires or coil. If so clean/replace them.

Good idea, though the spark plug wires don't have more than 5-6k on them... I'll definitely give them a look over.
thanks
