You riding dirty on 15s, lowrider style? I'm surprised you're not redlining at 60 mph running such tiny tires, but I bet the truck is pimping!

I corrected that to 20" wheels

Yeah, I knew what you meant, but I never pass up an opportunity to be a smart ***!

Guys I finally gotta test my 91 T4 tune from Shawn. Holy crap! This thing fricken hauls butt and sounds like 2000 lions roaring in unison when it goes! This 0-60 times in the under 6 second range ain't no joke. I was shutting it down at 70 and couldn't believe I was already there. Shifting was around at least 6100 rpm as I was looking at the road and glanced down. I was also able to get up to speed so smooth just cruising. I couldn't believe the response the truck has. I mean all Shawns tunes are like this its just that much better every time. I would still be happy running a T2 tune but when you can have the top of the line why not! 5.0 guys get on these T4 tunes. You will not be disappointed. I'm gonna try and get a dyno run soon. Gotta do some research. 1/4 or 1/8 runs eventually. I have never drag raced before so there will be a learning curve. Hopefully get some stuff done by end of November

A day after I started this thread Shawn emailed me saying than when he was looking back at my tune he had mistakenly put the T2 transmission stategy in my tune. When he was redoing the tune he said my spark tables were also setup for 87 octane. So those original videos were the difference between stock and an 87 octane t2 tune. The difference with that original 87 tune was .49 seconds. It went from Stock 6.51 to 87 Tuned 6.02 seconds.

The new 93 octane T4 tune ran 5.77 seconds. That is a difference from stock of .74 seconds 0-60.

Here is the video:

The magazine 0-60 time for a stock 2000 Lightning was 6.2 seconds.
The magazine 0-60 time for a stock 2001 Lightning was 5.8 seconds.

This 2013 STX regular cab is listed at 15 lbs. heavier but I find it hard to believe that it is not more than that. The frame is fully boxed, the bed sides taller and the whole truck is physically bigger. I have the 2013 STX parked behind my 2000 Lightning and the Lightning looks like a NASCAR truck compared to the 2013 STX.

I'm thinking about going with 4:10 gears like the Tremor instead of a supercharger since this is my daily driver. I am looking at reliability over all out power. I want this daily driver to be easy to maintain.

She's running good with basically just a tune.What is your gear ratio now??

LTNBOLT

The truck is a 2013 STX 5.0 with a 3.55 limited slip. It came with 18" wheels and 265/60/18 Michelin tires (30" tall). I put 20" hypersilver wheels with 275/55/20 Bridgestone Duellers that are 1.5" wider and 2" taller (32" tall). To have the same effective gear ratio as with the 18" wheels and tires I would have to go to a 3.73 gear.

So basically the 3.55 with 30" tall tires has the same effective gear ratio as 3.73 gears with 32" tall tires. It is kind of like I changed my rear gear ratio to a 3.37. If I installed 4.10 gears it would be like a truck with 30" tall tires going from a 3.31 gear to a 3.73 gear.

How did you measure those times? I counted you starting at 0:06 and hitting 60 at around 00:13 on the stock video which is around 7.x seconds. The tuned video you started at 00:04 seconds and it was hard to tell, but looked like you hit 60 around 00:10 which is around 6 seconds.

These times were measured with an old g-tech pro (10 years old). The newer models have a big display and cost about $200. The times are constant within less than .08 to .09 seconds of real time. I know because I have tested it at the track years ago with my Lightning and a couple of months ago with my STX. Every run was short .08 to .09 seconds compared the the timeslip ET. That is as consistant as you are going to get.

As far as the mph, I can't give a for sure answer on that. I know the g-tech always measures higher mph than the timeslip. The track measures the last 66' to the finish line to calculate mph. A timing beam is 66' before the finish line and then there is the finish line timing beam. My speedo in both trucks was always closer to the g-tech than the timeslip.

So you can bank on the stock tune being .74 seconds slower than the 93 tune. Did it get to a perfect 60 mph? All I can say is it got to the same mph everytime.

Counting a timer from an iPhone video is not an accurate way to measure anything. Are you reaching for something. Just askin'.
