3.0 Whipple 6.1 Misfire at WOT
Working on a customers 6.1 300 with a new 3.0l Whipple. Stock car other than LT headers/HC Throttle body. Originally he had whipples RTD tune in it but they had it scaled for a 2 bar MAP meanwhile his kit had a 3 Bar. Fixed that for him so it obviously ran much better however there's a misfire at WOT that we've been having issues with. So far he's fixed exhaust leaks, replaced injectors, regapped plugs from .050" down to .030". P0300 comes and goes and car drives great in closed loop. Im targeting 11.5 AFR at WOT but you can see in the log it hits target and then will bounce a full point away and then return. Any ideas? Car didn't have issues before he installed supercharger.
