Well i finaly got my diablo predator put on my truck tonight and i was pretty impressed with the increase in power off the line. I deff feel a diff from the stock tune. I guess what i was wondering is if any onehas brought there truck to a 1/8 or 1/4 mile before and after tuning there truck? I ran mine in the 1/8 a couple times with a mxp airaid full intake and a magnaflow muffler. The best time i could mustard up is a 10.10. J/w what lind of gains i could expect with a tune now?

 

I have dyno'd and ran my truck at the 1/4 mile track, both bone stock with no weight reduction on 87 gas. I did it for a baseline.

My results were 305rwhp/ 318rwtq on the dyno. Best 1/4 was 14.8 @ 95mph and the truck and me weighed 5420lbs on the track scales.

 

Given the marginal gains you will get this post really is not all that helpful. All trucks have slightly difference tollerances, different gears, cab configs, you have track conditions, elevation, fuel, temp/weather, ect. Those items alone can eat up all gains by the Predator.

They only way to objectivly tell is put it back to stock tune, not hard to do, make a run, then back to 87 or 93 and make a run. Do it the same day with as little time between them as possible.
