Good afternoon, new to the forum. I installed an Inertia SRT max plus cam in a 2009 Challenger 6.1 m/t and customer uploaded tune via Diablo that was sent to him. Is anyone here familiar with this camshaft and application? The car really struggles to idle and start but throttle response is spot-on in the higher end of RPMs when it finally starts. I'm not doubting the tuner's capabilities but I am curious to see if anyone could possibly point me in the right direction as far as a "base line" tune maybe? I'd like to compare/overlay a "known good" tune with the current tune if possible to see if maybe the tune did not upload correctly or something going haywire with ECM. We did have to upload current tune like 4 times with Diablo before it would even attempt to start. Bank 2 LT fuel trims instantly jumping to -33% when in goes to closed loop. Smoke tested, sprayed for vac leaks, swapped upstream O2s...any assistance would be greatly appreciated.
Mods are cam described above, cold air kit, long tubes, full Corsa exh. no cats.....and a TON of suspension upgrades lol (null and void)
