i TOOK A TEST FILE

 

so at first its just at idle then I let it roll on its own the I hit the gas just a bit,

 

Can you give us a list of all the mods?

Is this a cable throttle body, or electronic throttle body? If its cable you need to adjust the idle set screw back down, like, alot. If its electronic he needs to reset all the throttle settings back to stock.

I would be pissed if I paid $600 for that, fueling needs a lot of work.

 

Pacesetter 1 7/8 long tube headers. P1SC H.O. Intercooled. Warlbro 450LPH. Siemens Deka V 80lb/hr Fuel Injectors.
Its Electronic throttle body.

 

Sounds like to much Desired Airflow and/or Theottle cracker combined with no DFCO. IMO with FI you dont want DFCO. I know whem i go wide open then let off the gas suddenly i dont want it yanking out all the fuel and going insanely lean.

 

Insanely lean is fine, and DFCO doesnt pull fuel until the manifold pressure drops to a certain amount and after timing is pulled down. Rich is fine, and lean is fine, stoich is the hottest.

 

I'd like to say Thanks! To the following members. Atomic, Vortech350ss, 03Sierraslt and BlackGMC.. He will tune it again! Its was not SD tune, This time I will be over his shoulder.
