My tuner doesn't exactly know why, but he has found a way to make it so the lag isn't so bad. But it is still there, and he says for some reason it's limiting the throttle body from opening all the way when I floor it. I think he said it's only opening 80% or something. Any idea why it bogs?
Also, at a dead stop and I hold the break, I can only rev up to 1750 rpm. How do you get rid of that so I can rev it up a little higher and get a harder launch?
