anyone please help single turbo guys or twins...just recently got a new turbo just put on my car cold side .70 hot side1.00 i have the single turbo conversion well anyway my old turbo that needed a rebuild was a cold side.70 hotside .69 well i start my car up and the idling is around 400-500rpm and it was running rich then it started backfiring and stalling out and then the idling started flucuating.... then it ran very lean so i shut it off so i could prevent anything bad from happening...im very familair with everything and how it works but my maps on my pfs pms just can't be right... i never had it tune yet, i just left them as they were when i bought the car... no one around here really tunes that i know of.... i just really dont understand the mapping... my idle(fuel) is at -12% idle(timing) is at 0% part throttle fuel is as follows: 2200 (6%) 4000 (8%) 6000 (14%) 7800 (0%)
part throttle timing is as follows all zeros thanks guys if that makes sense

 

There are a few good shops around you that can help you out if it comes to that. Check the regional forums.

 

Yeah, you do have some very good tuners and RX-7 shops around your area.

 

yea if it is really complicated i will def take it to jpr performance or kd rotary just wanted to see if anyone else had exact problems and what they did thanks guys

 

just changing out a turbo with a little larger exhaust housing shouldn't cause your car to run like that. Is that all that was done since it was running right is that you took the turbo off the manifold and put another one on?

I also dont think too highly of using a pfs computer to run a single turbo which means you probably have stock injectors?

 

well yea thats all i have done was switch the turbos... i have 850cc primary and 1300cc secondary w/ supra tt fuel pump...
