Engine/Transmission (1998.5 - 2002) 2 Seconds Quicker

[RTrenary]

2 seconds quicker and 10 Mph faster in the 1/4 mile with the few changes that I've made. Last year and completely stock the truck ran a 18. 1 at 72 mph with 3:55 rear gearing



I had problems with spinning the dually tires, so I had to let the air pressure down and do a burn-out to warm the tires, that helped out, but had to come down on the boost alittle from the start so the truck would hook-up better, I never thought I'd have to do a burn-out with a dually, lets just say a few people took notice



the truck still spun alittle and the air temp was around 80 degrees

so there still alittle more in her!!!!!



The trans does NEED TO BE UPGRADED!!! the convertor would not lock in until almost the end of the 1/4 mile, new trans would put more h/p to the ground.

I love my truck!

My "baseline" run at Rockingham NC dragway test N tune last year was a blistering 18. 9 @ 73 MPH. Totally stock. At the time I was running an early Edge "3 light" box and boost elbow. That time is with the box off. The same day I ran a best time of 16. 4 @ 86. Weight was 6,740 at the track scales.

Since then I've installed Bosch 275 "RV" injectors. My best "GTECH" time to date is 15. 9@92 MPH. I have yet to run it at a track since the injector install.

It's amazing how a simple fueling module can shave over 2 seconds and add 12 + MPH to the 1/4 mile times!

And it's much more of a pulling machine with the box on level 1.

Mileage is 21 MPG average lately.

Have you got some weight in the back to help hold the tires on the pavement better?
