So, I was at the track on Thursday night, TNT. Racing started at 5:00PM. D/A ranged from a high of 1029 at 4:47PM to 670 at 7:47PM. First 2 runs were with the LMS, stage 4 tune from the SCT, the rest were LMS stage 4+ using a mycal tune. When I complained before that my tunes seemed to be the same, meaning, no advantage with the 4+/Mycal, the complaint was dismissed, because the runs were not on the same day, although the D/A's were virtually identical.
LMS, Stage 4, SCT tune
4:56PM #1
R/T .389
60' 1.924
1/8 8.472
MPH 82.39
~5;10PM #2
R/T .165
60' 1.905
1/8 8.451
MPH 82.53
From here, i switched to the LMS Stage 4+ Mycal tune
5:39PM #3
R/T .485
60' 1.924
1/8 8.469
MPH 82.81
5:43PM #4
R/T .334
60' 1.909
1/8 8.440
MPH 83.07
Then I jump to race #8, with the best times
7:08PM
R/T .525
60' 1.891
1/8 8.444
MPH 82.88
So, those were out of 9 runs. You can see run #1 was virtually identical to run #3. Run #3 should have had better times, since the D/A was probably lower (D/A @ 4:47 was 1029, and at 5:47 was @ 984). Run #2, which was closer in time to #3, was still better @ 60' and 1/8 mile, but not MPH.
So, you that are more experienced, it looks as though the stage 4+ is only going to get me a slightly higher MPH, but other than that, Nada. What do you think?
Although, I did beat a new Camaro SS and a CTS-V.
Those numbers are very interesting but before drawing any conclusions, I would think you should repeat this on a 1/4 mile track, I think you may see more of a difference in the 1/4 then in the 1/8. I don't have anything to base this on, just a hunch, that you may see a difference. I would at least try it, before making any conclusions.
You know, if I had a track that was in 3 hours drive, I would. You would think, where drag racing started, we would have a track. This is what I have available. I thought the same thing though.
Oh, this was also 3 gallons a gas, all crap out of the car (No spare or rear headrests), 2200RPM launch, front tires aired down to 30.

I was kinda thinkin' the same thing. Another gear or two to ride out with the sustained boost. Your 1/8s are pretty close to mine and I'm on 93 Octane. I think with better DA's we will hit the 12s. My dyno showed a real difference. Not so much more at peak torque, but a big difference in sustaining it along the curve.
Interesting... I wonder how my 93 performance high boost thermostat tune would compare tune wise. The XSports tunes are not called by stages..

I am sure it would do better.
