This was my second file, the first being the one with the major problem.
When I first loaded the second file on, it was an improvement but I still felt like it wasn't all there after a few miles, just rolling around locally to the gym or whatever but I guess that's not a real test. Today it's just settled itself down and become comfortable after a decent amount of country road and highway miles, and a pull on an M4 and some random R33 GTR.
My girlfriend talks a lot, but 2nd through 5th sorted that out
. Even she mentioned how much faster it felt from the passenger seat.

Just went from stock to ARH catless headers with the v7 tune, and I am having the exact issues described. In C mode, the clutch is slipping really bad, in manual the shifts aren't crisp and fast as they are stock. The car feels super slow, and laggy. I loaded the stock file back, and the car was instantly buttery smooth, crisp shifts, and felt faster than being tuned lol. Hope Jerry can help me work this out.

I’ve had my car on battery charge since about October and last weekend I took it off and out on the road again. I don’t remember it feeling this quick, I’m really impressed still with the V7 I have.
I’m sad some guys are still suffering, I don’t get why there’s such a variation between us and why whatever worked for my car hasn’t worked for others.

I did disconnect the battery overnight and it didn't really help me in anyway , Im going to try it again just for the sake of it . So load the file (v7) then just let the car sit for 8+ hours with it disconnected . I will report back and see if it gets resolved .

Ya, try it again. It didn’t work for me the first time I tried it either.

I think its wheelspin and he doesn't realize it. You hit the gas while on the move and rpms go up but car doesnt move then you look over and see the traction light blinking then look back and see a small cloud of smoke. I swore It felt like I lost power with v7 too.

Did you change your air filters? Another member had that issue after installing ROW airboxes and it was due to incorrect installation as the box wasn't sealed right and MAFs weren't reading accurate g/s of air leading to incorrect load ratings and transmission was acting wonky.
