Friend let me borrow it for fun. It has a dynometer and 1/8 mile run deal.
I tried it in 70 degree weather and it says i run a 9.9 in the 1/8 at i think 76 mph. it also said 284 hp but then i did dynometer and it said 255hp.
Anyone think its decently accurate? Its def fun to play with id never buy one though. I tried again tonight and its 56 outside and ran a 10.7 in the 1.8 because i was spinning and have skinny tires.
Mods are in the sig no hp tuners yet. its a 4.8 reg cab.
285 at the motor is prolly accurate. A 4.8L with no tune should be at that mark at the motor.
Yea i thought it seemed pretty accurate. I don't know why the dyno run part says its lower but not really sure what your supposed to do it just says go lol and i floor it.
When i get some more gas im gonna make some more runs to see if the 1/8 mile will be close to what it was the first time or not.
that 1/8 mile time at 76 doesn't sound anywhere near right unless u was spinning bad
no wasnt spinning to bad that time. every other time i tried though i just spun and spun. im off work today so im gonna play with it some more
you dont wheel hop with an 8 inch rear drop??? or is it an open dif?Quote:

Soon as i add some more performance parts im gonna use this thing again not for the tune but to see if my time changes any
my 4.8l's mpg took a nose dive with the hypertech tune. and performance was terrible, so i just left the stock tune in with the tranny pressure boosted and it was flawless. But!! i then installed the hypertech 87 octane tune on my dads 05' k1500 4x4 with 5.3l and it gets almost 3 more miles to the gallon. not really sure how that all happened. but its kinda hit or miss with generic tunes like the hypertech.
