We need to know more about your car.

Do you have an AEM EMS or Hondata?
Injector size?
Wideband?
What MAP sensor and what resolution?
What exhaust?
Cat or no cat?

I had an exhaust system on a previously made my car sound like it was sputtering, but the tune was dead on. Changed mufflers and no problem.

Ended up tuning the car yesterday. The map sensor was actually a omni power 4 bar, not a GM 3bar that I assumed he was talking about when i sent him a basemap. Also, #4 injector clip was not plugged in so the cylinder was dead. Car still made a 2 hour trip to the shop for tuning. Got the problems straighten out and made 340whp/220tq at 8psi.
good to hear jeff! This is jonathan with the black turbo s2k. Hope all is going well!
