I guess there lies the problem. After moving Back to Hawaii, I have no idea where a dyno is let alone a good tuner. Is the sct setup hard to understand or learn? I use to fool around with a vec 2 when I had roe blower gen 2.
Thanks again.

There are a few but I got mine from Dan at Viper Specialty. He is a very good tuner and works with your dyno results and makes changes for minor or major changes. My gen 3 below:

That's some major aliasing going on in that dyno. What's up with the readout?
Also, at 12.44 AFR are you all motor? It's OK to run that high, but I like to see the boosted cars closer to 11.8 or so. All preference I guess.

No weight yet, I haven't bought scales yet although I definitely should. I don't even have a weight on my Cobra and I'd be much more curious about it than the Viper.
Those runs were BEFORE final tuning... it hasn't gone back on the Dyno yet.
I don't know what happened on that particular run as I wasn't there, but it was the only odd one like that if I recall from the copies I received.

Yea no offense intended. I've never seen our dynojet do that, only reason I asked. I am in the measurements field for a living and just surprised to see such a regular wavelength/amplitude on a dyno. Looks like a shielding or loose connection issue; that or some sort of interference.

It was a loose lead. I only posted it because it gained a few HP. All NA. Corvette injectors and wires. Lambp intake and exhaust. Porsche throttle body. Mata air filter.

Had to add a little humor there. Actually its a Paxton setup. I'm very happy with the results as far. A little more tweaking and we're there. Dan at VSP did the advised me from the start thru tuning and has been extremely helpful all along the way.
Cheater. Not everyone is going to be putting them on loose, pointing the air nozzle at the intake, sucking on the Baro sensor on the Dyno so it thinks it is on Everest, and running on the rollers along with the car for that extra "ooomph".
I still don't believe you... those peaks are just when your feet were hitting the rollers.

Wonder how much more power a 3" diameter piping exhaust with no cats would put down

I would see that being reasonable.
Who has a set of factory exhaust connection pipes (cats) that I can weld in a straight pipe and test it on the dyno? I'd likely weld one set at a time, so comparison of both sets of cats, 1 set of cats and no cats.
Not to mention weight savings. if memory serves each cat weighed in at a hefty 20 pounds on my gen 3 and the replacement straight pipe weighed in at 7 pounds each side. so 26 pounds weight savings and again if memory serves 15 rwhp on the dyno. i was more impressed with my 99 viper by straight pipeing the cats. 20 rwhp gain and that was the only mod for that dyno run ...
99 rt10 400 stock
410 with smooth tubes and kn filter
422 with harland sharp rockers
440 with straight pipeing the cats

Ooops..18 rwhp. still great result
03 srt10
457 with kn intake and harland sharp roller rockers
then sold the kn air intake (dont ask why) and put on stock filter with kn filters
476 with stock intake and kn filters/roller rockers/sct canned one size fits all tune/findanza flywheel/underdrive pulley/titanium exhaust with cat delete
i did just the cat delete on a differant srt10 and gained 1.5 mph and 1 tenth with quarter mile testing

Wow this is great info. I just did the K&N (no tune) I was going to do some Corsa exhaust but now.... I think I'll do some shocks first on my 06.

Deleting the crossover pipe greatly improved interior heat, but I didn't even notice a significant change in exhaust tone.
Best of luck!

What exactly is the Corsa Exhaust, Is it a catback system with high flow catalytic converters?
