Jorday, get a quad 135 or 165 tuner or a bullydog 150 tuner (they raise rpm above 3200) and stack it with the juice. Lock out 5th gear and you will be in the 13's and not have to worry about 5th gear slipping

 

04Denali: That was a very good night for racing. I should have thanked the Mustang guy for leaving his rear on the track. The traction compound they sprayed after the clean up might have helped my 60' and ET. Shoot me an e-mail if you need a Volant. We have plenty in stock and I'll take care of you on the price. It would arrive in a day.

The Duramax guys just need a few mods to make those trucks fly! They also have the benefit of good gas mileage to and from the track.
