Edit : or if I uploaded mine to see what the differences are between the two? I'm having a a problem with boost cut in 3rd gear then CEL comes on. 2nd gear you can hear the car regulating boost constantly causing the car to surge some.

Thanks

Resetting adaptations and following the read me file may help if you havnt already done so.

Have there been any other modifications to the car? Perhaps it may be a boost leak?

What are the codes.

Hey guys, no codes at all, I was turning the boost up. It's set around 18lbs, got it running way smoother adjusting some things but didn't know if there was a specific map for these mods that people have gotten the best power out of.

Thanks
