But I was way up on mph from 122 to 126 and best of 127.5 for day from a best of 123.7. Maybe you also noticed it seems when I spin a little my mph goes up vrs moderate wheel spin or even too slow of a roll on and no spin at all. All of my best et are down on mph. Tm is just way to sensitive and if you had hptuners and could look at the last logs I did it’s redicilous how far the throttle stays closed and how much timing is pulled on shifts. Can take 10mph to get full timing back again then shifts and plummets again. I wish winter mode was like my caddy where it starts in second gear as then you would have a longer time on launch before a shift which then has the big timing drop. I might try soon as I roll out grab second maybe even third And let it just pull through it. A buddies twin turbo 5.0 went from high 1.68s to constant 1.50s just doing manual second gear starts. Wouldn’t over power the tires so easy but had enough to to get going good with a wot launch on boost. This car cannot command second at a stop which sucks as really think it would help. A 1.65 on this car will be 10s.
I was supposed to go today but something came up. I'm definitely going tomorrow. I'll keep you posted if it's good news
