I have quite possibly tried over a thousand different tunes. The biggest successes were replacing the throttle body, with the same whipple throttle body. That netted another 6 months of use, before it would start going into limp mode again. And when I replaced the bypass valve, I really thought that was it. Until I went to pulley down again. I have tried NN on and off. I have done some weird shit, that would sometimes get another 200-500 rpm before cutting. I just checked my folders for this car, I have 738 files for this car. That's a combo of datalogs and tune files. Many many 2 am nights trying to get it figured out. This is just about the last attempt on this car. Chances are, I'll put the smaller pulley back on, make a shitty 945 hp, and fire sale the car. Although, everything worked pretty damn good until the whipple. I've tuned several stock blower pullied hellcats to the 900 hp range. And they ran great. This is the only big blower hellcat for me. I've tuned several other mopars in the past with kenne bell's and prochargers with minimal problems. I always resolved the problems. And the hellcat is whole different animal (get it, animal?), so I expect some difficulties. Which is why I have payed a few thousand dollars to other tuners to try to resolve this. I was just always left holding a steamy bag a shit, just more in debt. Sorry if this is coming across with a frustration tone, I'm just at my wits end here.
I've seen other people have issues with the hellcat and whipple, while searching here, and no one posts tunes. So at least, I'm posting a tune. I'd post more tunes, but it would be next to impossible to navigate all the tunes for this car. But if for some miraculous reason I get this figured out, I'll post the tune. So just in case someone else out there is having these issues, they have something to go on.
