I am also having this exact same issue with a 2011 silverado turbo TH400 swap. Did this ever get resolved? Anyone know the fix for this?

It's been hard to get this Jeep back as it's my client's daily. I was able to try a few different tunes a couple days ago but I'm still having the same issues. Since this Jeep, I have now done...

Thanks for the replies. Jay I did try reseting the adaptives before I start with no luck. Hemituna I'll try that, I think I already tried something close to that but I'll give it a shot again.

From what the owner knows this is what I got. Built engine stock displacement 5.4, ID725 injectors, Whipple 3.4, stock MAF, Ford racing twin 63.5mm TB, Ford Racing standalone harness and ECM, long...

Thanks 15PSI, I took a look at some of the tunes. Not much there and nothing really different from what I have.

I have an older Ford with a built GT500 engine swap and a 3.4 Whipple. The car starts and idles decent but struggles to rev past 3500rpm. What I`m noticing is that the engine will accelerate...
