I've got a weird question. I own gto. This is for a friends car. Its my understanding that the TBSS has the E67 computer. If I'm wrong I'm terribly Sorry.

If this Is true. Have You boosted guys had trouble with KR? Even on a very conservative tune he is having issues. No matter if its 5* or 15* of timing, when he goes into boost they keep getting KR. Afrs are mid to low 11s. Its a grand prix gxp with the 5.3 litre ls4. I know they are different but we were hoping that this is a common issue. The 08' was the only year to get this ecm so he can't really compare to the other years.

The tuner he is using very smart and has a perfect Rep. So we are hoping its something that's ecm related and we just don't know the fix.

HP tuners has been helpful but we can't seem to figure it out. I told him I'd poke around the TBSS guys and see if I can dig something up.


Thanks

Kyle
