JLT + AED Tune before and after
Just got back from running at Bandimere for the last time this season. Was great, almost nobody there and I got 11 runs in a little over an hour lol. Prior to the intake and tune the best time I managed was a 14.015 @ ~102mph with a 2.1 60ft. I'll go find that timeslip and upload it later.
After the intake and tune I have a new best of 13.43 @ ~105mph with a 2.05 60ft. For comparison there was only one other 5.0 there today, he was trapping 100mph today and running low 14s. Think it was a stock auto with mufflers and springs.
The funny thing is I had it dyno'd on the stock intake and tune and then swapped right over to the JLT and tune and ran it again and there was almost no difference on the dyno.
Run 1 is completely stock and Run 2 is JLT + AED tune:
Shaun at AED was great to work with and got everything to me super fast, the car drives just as smoothly as stock. The guys at RWR motorsports were awesome too, they datalogged my car on the dyno and sent it to Shaun to verify everythings running well and revise the tune if need be.
Although it didn't show gains on the dyno it seems pretty clear I gained power with the tune by the track times so I'm happy.
Disclaimer: I live in Colorado at 5800+ ft of altitude which is why these times are super slow

Yeah I'm not putting too much faith in the dyno numbers considering the stock run was 410rwhp. Way too high. Maybe it has something to do with the correction factor being 123% lol. I'm more interested in the real gains it made at the track

Those numbers post tune arnt too crazy, defiantly not 410 wheel stock. I have seen a all stock 5.0 make 420 wheel just with a dyno tune, than again like always every dyno is different, be it happy or not.

Honestly I was just underwhelmed with the performance of the boss compared to the GT given how huge the price difference was. The handling was better on the boss but that's about it as far as noticeable differences daily driving. I sold the boss for more than I paid for it and im supercharging my GT and adding better suspension than the stock boss. and I'll still come out spending less than a stock boss.

Your dyno numbers are very interesting. Normally a larger diameter CAI like a JLT or Steeda would show a 12-15 horsepower gain due to less restriction. However, at your ridiculous altitude the air is so thin the stock CAI no longer poses a restriction. Using a horsepower calculator just the altitude alone costs you almost 80 bhp so at the flywheel you go from 444 to about 366. Ouch! I noticed this when I did the Boss Track Attack last summer. Miller Motorsport Park is around 4300 ft. The cars didn't really feel very fast. They literally could not spin the tires, at least at the 3500 rpm launch speed that the 2-step was set at. Dyno correction factors are great to account for the 110 degree summer heat where I live because I know I'll get the power back when the weather cools off. Unfortunately there's nothing you can do about altitude. For you forced induction is a necessity.

I will admit, I'm a little surprised at the dyno numbers. I would think with the JLT and an AED tune would yield more horsepower than what the dyno is showing.

I have a feeling that once you get into correction factors that high precision becomes less. The air at 6000 feet is so thin I'm sure the restriction of the stock CAI is negligible, whereas at sea level it is quite significant. I had my car tuned at AED and got a peak gain of 7 hp. Later I installed a Steeda Boss cai and gained another 13 for a total gain of 20 hp. This was all on 91 octane. I'm guessing I would have seen maybe another 5 hp with 93.

I see, just looked at the top number. Not sure why their so close. Still 415 wheel is like 470 crank, I'd love to get that out of a tune.

I think extrapolating from chassis dyno to crank hp is close to a guessing game. My corrected baseline on Shaun's Dynocom was 404 whereas on a local Mustang dyno it was 387. In the case of the OP I think the extreme altitude basically nullified any benefit from the JLT.

Yes the first run is completely stock and run 2 is intake + tune. I gained hardly anything on the dyno but dropped 6 tenths and gained 3mph in the 1/4 mile
