What gears were you running ? Here are the numbers 413 TQ @ 4700 398 HP @ 5700 . I do a lot of highway , 100 miles a day when I use the car so getting a high stall converter always worried me ,gas is about $7.00 a gallon .
i was running a 3.91 gear and using a 26x9.5 tire when at the track..
well if you get an efficient converter then it will feel like a stock one running around on the street, hell it may even feel better then what ya have now..:). something built into your combo from a place like dynamic, ultimate or ptc. but driving like ya do there will always be a compromise.
