What up guys? I been trying to get my car tune with the AEM COP,twin fire and gt35 turbo. engine sound great and we can get to boost 10psi. But wen we try to add boost more then 10psi the engine sputter at 5500 RPM. Everything in the map looks good and we all ready contact AEM and show them the map. They say there no problem with it. Any one have been in this road before with the COP? Any help ?

Is timing drifting?

Good point, what trigger are you using or stock dissy? I sacked the aem epm off for the T1 trigger after hearing a few people having problems with what tama mentioned.

I had a faulty AEM EPM puck...causing all hell with the tuner. He was told by AEM nothing was wrong as well, but he ordered a new one anyhow, bam problem solved.
 
I'm using AEM cop pencil coil with the AEM EPM and the spark plug gap is 21. I don't think the timing is drifting but I can not run to much timing because is not low comp. I'm goin to try CBR 1000 coil to see what happens.
