HPE Tuning Results with stage 3 cam, 562 rwhp!
I've tuned 2 with our stage 3 cam so far... The car from the video I put on our Mustang dyno. The second car I tuned between 2 different shops, one of them being Vette Doctors in New York.
Car 1: HPE Stage 3 cam, Kooks headers, ported throttle body, no cats.
stock tuning: 515 rwhp, 447 rwtq (HPE Mustang Dyno)
tuned: 531 rwhp, 462 rwtq (HPE Mustang Dyno)
Car 2: HPE Stage 3 cam, Vette Doctors Headers, Ported throttle body, high flow cats, mildly cleaned up heads.
stock tuning: 522 rwhp, 444 rwtq (Vette Doctors, Dynojet, NY)
tuned: 562 rwhp, 498 rwtq WITH the stock air filter in place (Proven Performance, Dynojet. Milford, CT)
We're doing another stage 3 at the shop right now, and then I have a stage 3+ I'm gonna be trying out in a car from Florida. So it should be interesting, but so far these seem to be responding well from tuning.
I tuned one with a smaller cam, and it went from 505 rwhp, to 522. So I'd say 15-20 rwhp gains will be the norm, but others might be more. Just depends. But I'm pretty happy with how everything is working out. Ken at Carputing has been great so far with getting all the bugs in the software lined out, and right now we seem to have a pretty solid program.
Any questions just give us a call at the shop. 281-448-1300.

Nice numbers!! There's a significant difference between Car 1 and Car 2. What do you attribute it to? Headers? Head work? No cats should be better than Hi flow cats, but aren't in this case. (????)

It would be nice to see the two cars dyno on the same type dyno, ie the dynojet. Either way, those are nice gains in power.

Plus head work must contribute as well.
Awesome numbers

I'm not sure by how much, I've seen results all over the place.
I think it's best to use dynojet results for comparison purposes.

Since both cars are from out of state, it'd be hard to dyno them on the same dyno. And the one I tuned just went back to Dallas a few days ago. It made 554 on the dynojet before tuning. So I'd say it would probably be at 565-570 now on the dynojet after tuning. However, load plays a big role in the a/f mixture of a car. The Mustang dyno applies load like it would be on the street. A Dynojet is just an inertia dyno that measures hp based off acceleration (with a drum that weighs approximately 2500 lbs)
Basically, the less the load you apply to any given tune, the richer the a/f mixture will be. So I've seen cars pick up hp on the Mustang, and not show any difference on a Dynojet, simply because it had more fuel than it did before. I could tune a car on the dynojet and pick up "numbers", but it wouldn't necessarily run right on the street because the load was different. That's why a lot of times you see people tune a car on a Dynojet, and it runs great. No detonation, or anything. (This is especially true with people who tune trucks on Dynojets...) However when you get it off the Dynojet, and onto the street, it detonates. That's because the Dynojet doesn't load the vehicle like it would be on the street. Which is why I choose to do all my in house tuning on a Mustang dyno. Dynojets are just toys that measure hp

First, great results!
Second, I still do not understand why car #2 w/cats had basically SAE 30rwhp and 30rwtrq more than car #1 w/o cats. Seems very strange. Are you saying this is a dyno issue? I.e., different types of dynos on different days? Because the same type of car, with same mods should be very close.
Thanks!

Good explanation on the dyno comparisons. This is why we bought a Dyno Dynamics eddy current brake dyno!
What about the "mild" headwork you did?? What is considered to be mild?
