Just to see is everything ok, car has no known issues. Stage 2, with around 1,3 bar backpressure at 6500+ (bad exhaust)

Datalogs on dyno with Littco tuned (Dan) Made: 513hp 602nm 354whp & 507hp 606nm 350whp Pretty substantial power loss. But as far as I know we should only look at hp E74 Notice: timing creeping in when going on boost Notice: correction values. 2 options - Tuned to the max or problems with the timing map. Car feels ok, no known big issues.
