The truck starts and runs fine, you can take off easy and it's fine on the economy and 120 tune. Now when you floor it and run through the gears it bogs through the mid range and the boost fluctuates between 12-20 then kinds cleans up and will hit 35 on the high side then it will kind of flutter till you shift. It throws a PO326 which appears to be map related.
We installed a air compressor regulator to try and fool the map to see of that would help and it didn't.
I am kinda stumped here. We don't want to throw un needed parts at it but we are open to suggestions.
I have a good array of tools so if you have any tests I can try that would be great.
Well perhaps that's an issue then. This is my friends truck and we assumed TS tunes would make this combination run better. Any suggestions? It really stinks having all these performance parts not working together!
