Update - so I have the GH tune in, extra quart tranny fluid and correctly gapped plugs now. Been running it for a couple weeks, and probably have roughly 200-300 miles or so. Before I uploaded the tune, I did a kam reset and it’s definitely improved and adapted since then. BUT (and I’m starting to think it’s a mechanical part on my car and not the tune, since the tune is fine for everyone else…), it still does this funky hesitation/shuddering shift, which is more prominent with WOT and accelerating around turns. 1-2 is butter, 2-3 is where its the roughest and 3-4 and so on are also kinda choppy but to a lesser degree. As I stated before, me transmission is new from the dealer as of 20k miles ago. I sent in a log to Matt and he said the only thing he saw was that my torque converter was having trouble locking. I read up on torque converters and the symptoms and I guess it could be that. Anyways, my update is that GH is much better than LMS, but I still can’t drive the car WOT or “freely”, I always have to be cautious/mindful how much I’m accelerating and the timing for it to not shift so hard. It’s also not consistent - one time I can go 2-3 with 90% acceleration and it’s relatively fine, then next it shuddering into 3rd gear and it freaks me out. It’s drivable no doubt, but I wanna be able to get it to shift like butter whether I’m going around a tight bend and acceleration or doing a 2nd gear pull starting at 3000 rpm’s and pinning it. Any other info is greatly appreciated thanks boys.
