All runs were made at the same boost level, peak around 19 psi tapering to 17.5 psi by the end of the run. All that was changed between the runs was timing advance. e85 is amazing stuff and as an amateur who does my own tuning, I love the safety cushion it gives you to go aggressive and find MBT. Break up on the first run was ECU pulling timing thinking there was knock. Picked up the 48 trim turbo for dirt cheap on craigslist so figured i would give it a shot. Really pleased with it. makes great torque (~200 ft/lbs at 3k rpm since everyone loves that metric). Doesn't feel too far off from my 2560 just with way more top end. timing was ~17-18 degrees at peak torque and 25 degrees at redline. AFR was around 11.8 - 12:1 (gas scale).
It’s a riot to drive for sure. Been a fun learning process getting to this point. Certainly money to be saved by going all in from the start but if you enjoy tinkering and testing and don’t mind spending more money in the long run then there’s something to be said for building things up along the way.
the 48 trim was one of those things that there was basically no real user data on. Glad I can throw another data point on here for someone else to leverage.
I need to get my GT2871 on my Absurdflow ramhown back on my car and see what numbers it puts down. I know 9psi was roughly 215whp at York Automotive.
Excessive Motorsport in Manassas. It’s a mustang specific shop. Good Dyno set up. Ground level, huge read out screen. Chris the owner just stood outside the car and operated the Dyno while I did the pulls, logs, and tuning.

Never heard of them, but there were always shops coming and going on Euclid. Check out PTuning in Manassas sometime when you get a chance. The have one of the best dyno rooms I have ever seen. When I hung out with them in 05-09 they started out on Euclid Ave before moving to their newer much bigger location.

I've actually been on the Dyno at ptuning, York and excessive. Like I said l, I enjoy tinkering and testing 😀
80% on the Hydra but in Hydra, 100% is more like true 85% duty. So actual duty cycle was probably more like 65%
How much more timing did you find you could run on e85? I made 296whp/302tq @18-19psi on my gt2560r and I was running 11-12* at tq peak tapering up to 17-18* at redline on 93. I have a 84.5mm bp4w, squaretop, 3" exhaust, etc.
I run a hydra 2.5 which I think is pretty similar to the 2.6. Hydra isn't the easiest to tune with but once you get it dialed it's great. My car has been problem free for almost two years now, and hydra gets a lot of hate but it works.
Edit...I see you were running 17* at tq peak up to 25*... Missed that in your first post. That's a lot more timing than I can run on 93, lol. I get knock at tq peak with anything over 13-14*.

In short, ALOT more timing. I was probably running around 13* at torque peak and 20* at redline on pump 93. I too would pick up knock at torque peak if I tried to go farther than that. With e85 Im running around 18 at torque peak and 25* at redline. Each degree I gave it was adding ~6 hp or so. Kept advancing until the gain was minimal (~2 hp per degree) then set it back to the timing prior to that run. Car probably would have been making mid 280's on the dyno I used at the same boost on 93. So its safe to say on this set up e85 and timing was worth about 30-40whp through the entire curve. this puts e85 at the top of my list of bang for the buck mods. the peace of mind with e85 is also very nice. On pump I always wanted to give it just another half degree of timing because I knew there was still power there but that always had me on the verge of knock.
As for Hydra, I think it works quite well. My car runs and drives great and its been running on Hydra and various setups (injectors, turbos, fuel types, motors) for over 3 years. A lot of the hate here came from its pricetag, which was a non issue for me since I bought it used. But like a lot of things, the masses just started regurgitating what others were saying and the hate took roots. Thats my theory at least. Functionally, Im not sure its really missing anything (except flex fuel in 2.6) and probably does a few things better than MS (knock control perhaps).
