I agree with you tissimo..tissimo said:
Very laggy, for only 400 whp you have the powerband of one that would be 550 on pump... not trying to put you down just want to make you sure there is could be a problem there that you may want to look into!! I know when I had my t04b and I had the same type of powerband I dind't have fun on the street with it. When I upgraded to a SP63, i actually ended up spooling faster, and making more power with a .58 hosing on it.
The t04b had a .84... but man was it much more fun.
