Dyno Run after Supra MAF/Dats Y-pipe

Alright, well let me first start off by saying that I know these numbers are skewed (no two dynojets are the same and they'll both give you different numbers even at the same settings).
That being said, I finally got around to putting the Supra MAF on and was finally able to get it dyno'd. I've had Dats Y-pipe on there for a while and got Midias's high-flow cat on there just a couple of days ago. Again, some may call BS, but I refer you to my first paragraph....
After a series of pulls, after saturating the engine with fuel (40%) across the spectrum starting at 3000RPM and retuning from there (based on Gabe's recommendation), ended up at 355HP. We let her cooldown and take a break before we started fine tuning. We actually de-tuned my A/F ratio from 12.5:1 to 12:1, again, based on Gabe's expertiese.
Once we fine tuned it, pulled 368HP/322lbs. of TQ...
He had the computer on "SAE" (Simulated Automotive Efficiency), which I asked him to put it on, so I could give you guys a comparison for what kind of a gain you'd be looking at with the Supra MAF and the Y-pipe installed. He now keeps the computer on "uncorrected," which the max the car pulled on that setting was 226HP, which I know isn't right.
So, with the same shop, same dynojet and de-tuning slightly...the Supra MAF sensor, Dats Y-pipe, and Midias's high-flow cat....I gained 82 extra HP and 53 ft. lbs. of TQ.
*Gabe, you were right when you said that MAF sensor was a beast. And sorry I didn't call you while I was in the process, forgot to bring the number.
**I did take videos, just need some time for them to be "approved." Will post when their done.
