I have one of the old radar detector looking gtechs that I have found to be accurate to within a few tenths.

Truck & Mods: 07 double cab 4x4 trd 5.7 with magnaflow exhaust, modified (elbow removed & additional 1.5” air hole drilled) stock air box with drop in filter, self ported (sharp edges smoothed out) throttle body, unichip piggyback (set up for airraid intake & exhaust) with switch set for maximum spark advance & high octane fuel.

Run #1 (2wd vsc on) – similar to what I would expect the average driver/tester to run
6.02
14.59 @ 99 = 94mph

Run #2 (4wd, brake boosted & stall flashed)
5.54
14.02 @ 102.6 = 97 mph

Run #3 (4wd, brake boosted & stall flashed)
5.60
14.06 @ 102.6 = 97 mph

Run #4 (2wd, vsc off, very good/lucky launch)
5.58
14.06 @ 102.9 = 97.5 mph

As you can see the times in 4wd (runs #2 & #3) were very close. The temperature was about 65 degrees at about 400 foot elevation. I only had about ¼ tank of premium in the truck so that probably helped too.

When I get a chance I am going to see what it runs with the airraid installed as well as without the unichip.

After owning a number fast vehicles over the past 10 years or so my butt dyno would say the truck feels like a low to mid 14 second truck so that goes along with my results. The truck doesn’t pull real hard at higher speeds, but it launches pretty well due to the low gears and 6 speed tranny.

Looks like the chip is dialed into your truck pretty well. No way you are going to get a 14.0x without it......... Congrats !!!!
