Took 4 pulls at the local place. I wanted to wideband it as well, but since I don't have an O2 sensor bung anymore (O2 sim after catback put on), I didn't have anything to hook it up to.
From top to bottom on the chart:
1 Hypertech with 87 octane power tuning
2 Stock programming
3,4 Hypertech with 93 octane tuning
Car was running it's usual Chevron 91 octane I always fill with. Temperature was 86*, and Tucson's at 2600 ft altitude, for those of you comparing numbers.
Here's my dyno chart
I like the low end torque, explains why the car is so fun coming out of corners in autocross and road racing. But you can see how badly the mild (.413/.408 i/e lift) stock cam breathes up high. Also showing I'm making nice power compared to the 200 flywheel hp the engine is rated at, no wonder I can take all the other bolt on V6's [img]smile.gif[/img]
Btw, mods are: Fast toys ram air, K&N filter, whisper lid, descreened MAF, high flow cat, 2.5" exhaust, and dynomax ultraflo muffler.
I think the smooth curves validate that descreening the MAF is ok on the straight TB cars, as long as you've done the right things to cut down turbulence, mainly the whisper lid.
But the Hypertech, now there's another story :mad: Absolutely zero difference from stock -> 87 -> 93 tuning. Looks like anyone trying to sell one is going to need to pull up their own chart proving real power gains, otherwise I have a bum unit.
Looks like Hypertech is going to get some email. Here's their claims for a 2001 Camaro.
As always, feedback and comments welcome.
