Hey whats up guys ,
little preface to start off , the car is a 2017 hellcat, MMX max effort cam,american racing 2" headers, id1050x, fore triple pump full return system,direct connection redeye demon head kit,arp head studs, 4.5" pulley and it makes 18psi QUICKLY .
The whipple 4.5 is a beast of an sc , Once I figured out the throttle blade was sticking partially open on some of the big oval tb's tuning wasnt too bad, that said there are still issues im battling and my tuner has basically bailed on finishing it, and on top I've actually fixed the limp p12B code on it myself along with the o2 transfer delay for the 2" headers, I get the tuning part since Ive been tuning my own Ls stuff since the 1st dongle hptuners made , However the dodge stuff is very new to me and very expensive to break lol.
Im not sure setting the tb to the oem airflow or the large and small range tables is correct , theres no tb lag but I cant help but think that, that isnt contributing to the issue.
The other problem is upshift/downshift spark reduction on my car is a sawtooth causing the car to buck in the 2-4th gear range, Im not sure if its just that or the tb too.
Its super annoying with a one piece driveshaft, has anyone figured out how to the fix that or is it still another $1200 secret for someone with whipple 4.5L experience?
