Mine was running 7800 Rpm’s now I have 200 miles the RPMs it will flash 8000 to 8100 and settles to 7900 to 8000 constantly. Running stock belt 192 1450 trigger studs only change I have done is a bigger intercooler that is good up to 350 hp and aluminum charge tubes from my 900t. It came in with out engine ECM and dealer installed it.

More miles I put on better it seems to run.
Winner winner !! Intercooler is not big enough on these 180+ hp sleds + understudded sleds overshifting and now you never recover .

We have another mach in our fleet so 3 of them. 2 of them were identical at 7400-7600 at best out of the box, both early builds, just added another mach, late build and it pegs to 8000-8100 every time and feels much stronger than the other 2. Im now convinced this is not clutching, its in the ecu but we are going to try a tial wastegate on one of the slow ones to see if it makes a difference.
Brent can you just swap the ECU's , tether? ,Gauge? And narrow it down ?
