See actually i have the exact opposite effect when cruising in first gear... I can go down to about a thousand rpm and slowly press on the gas and it goes away smoothly. But i am also only about 280 horsepower. So that may be some of the difference. First gear is really the only tricky thing. You can't really slip the clutch much so i just give the car in front of me some extra space and release the clutch. But it is good to hear it can hold that much horsepower. Not that i will ever get that high but i do plan a few more mods..
