Smoothing at zero for you (5 is default, I hate 0 for doing quick comparisons at at 0 you can 'jumps' that can produce false higher HP numbers. I've dynoed over 200 cars, and 5 seems to be consistant.

Care to circle what you mean here? I don't mean to sound dumb here, but I really am unsure what you see here (aka: I'd liek to learn) IMO some of the 'fluttery-ness' is due to the wastgate, not the tune. You should see big power Supra graphs...combined with what you can hear is amazing with the gate opening/closing.

Where you peaked on the jwt tune at 10 psi is in the area where the spark was not reconised and it caused an error condition on the dyno, you see where the breaks are on the graph? That could have been blow out or a miss fire. Probably fault of the car, not the tune.

Again, the difference at 10 psi IMO is related to the dyno, and not the tune at all. I can change correction factors to show you this (I can email you the run files, you just need Winpep7 which is free). I can also send you the 5 dyno day's we've run to compare across 3 power pulls. Anything in the 5hp range of difference is 9/10 the dyno itself, not so much the car.
Lets also not forget the differences in where I started the pull (1000 rpm difference, I forgot)...this can easily effect the 'low end' as youv'e got the turbo lit already. You should see me stab turbo hondas at 2k...it's amazing to see how crappy they are under Vtec...gross! I guess it's part of the game though right?
(And yes, I know about the spark pickup issue, unsure what that occured on the run...I just looked over all of my graphs and other sr20 and never saw it. Musta been a fluke)

The 20psi run on the jwt ecu really impresses me because before I got into tuning I had blown an sr up on a jwt tune and it didnt look any where near that good on a .86 2871r and a very similar sr setup. It does not look like they have improved much on their lower psi tune though.
All in all, these are much better results than I expected to see from either of these tuners considering neither of them have actually ever seen your car. I am most impressed with the Enthalpy because it is so smooth I would believe that someone did a custom tune on your car if you were to have not disclosed that it was a commercial tune. It is apparent how much safer that tune is for your engine as well.
Thumbs up for doing this!

As copied form another forum
"In the end of the day, both Enthalpy and JWT are fantastic companies. My point was not so much to show the difference (as I never would have epected such a difference at 20psi) but to show how close they really are in regard to tunes. I love the fact that these two companies support our community with bad ass parts for the 'street crew'."
Also remember that these cars are not 'tuned' for any specific PSI -they are MAF cars, so both are going to scale according to airflow. I always tell others to 'tell JWT/Enthalpy to 'tune' at highest boost' as the rest just falls into place.
I just am shocked at how close they really are. Again I need to get my ass in gear and get new chips for both and test them again, should be bad ass!
