I have a 2020 scatpack with a ported manifold ported throttle body cai stainless works long tubes no cats and mmx max effort cam the shop i brought it to did a regular tune on it to just get it running its still surging bad when i start the car and it jumps foward when i put it into drive (sorry its not manuel). I reached out to have them fix these issues plus put it on the dyno to see what the car makes and completely dial everything in and im getting no answer. Wondering who i should go to within new york or a neighboring state to fix my issues. My pcm was unlocked by dusterhoff useing hptuners.
Big Power Racing on Long Island has alot of experience with late model mopars and does dyno tuning. They are going to be dyno tuning my 72 Barracuda with my Holly Sniper setup.
If possible reach out to Jimmy at True Street performance or AJ Hemi tuner. They work together and AJ is one of the best tuners in the Gen3 Hemi community.
