Ill get some vids later. Pedal feels a little more responsive and added a little speed to my 1/4. Havent checked out the how fast i can go without the speed limiter i juts turned it up to 161mph so we will see later. Doubt it goes that fast.
Just an FYI....check the speed rating on your tires before you do high speed runs. Most of the all terrain tires for our trucks are only rated for 112mph or so. One high speed run every now and then isn't bad but I wouldn't go over 130 with tires rated at 112. Most of the gains you get from a programmer will be from the firmer shifts. Don't get discouraged from your first test run as those are pretty good numbers.
Premium and maxed out my shift points. Thinking about leaving all that be and just using Premium or just adjust 2-3 shift points.
Nice I hadn't really done any data logging on my truck (yours is nicer since it mounts up and the SC is hand held). After seeing this thread since I had the premium tune loaded in my truck I decided to go do a speed run 0-60 on a slight incline, I hit 6.31seconds...So I'd think you'd see better numbers be a reg cab. it's so hard to find a 1/4mile flat straightaway in Northern NJ without traffic or massive pot holes lol. I am resetting my truck back to stock tomorrow since it's going to the shop on friday ...so I may try a stock run.
On your GT, can you adjust your Torque Management, if so you might see some better 1/4mi runs...also your runs might get better after a 100 miles or so once the computer gets used to the tune. Keep us updated, good to see other numbers from other tuners!

My personal best according to my g-tech is a 6.64 to 60 and a 15.0 sec quarter mile at 90 mph. My superchips logged the same numbers when I did that run.
No I can only adjust shift points and rev limiters. I have another question if you guys can answer. You can turn the traction control off with the GT so i should be able to lay a posi. I tried yesterday and still only one tire spun. Do i need to back up a little first like you do with the chevys?
