Dyno after Boomers flash and Magnaflows

Just installed within the last week the Magnaflow cat back 170 t-stat, and Boomer's flash on my 2004 RC. I was wondering if these numbers are any good, since I didn't have her dynoed stock? The dyno was a STD not SAE.

1st pull 417.31 rwhp & 484.93 rwtq ran her in 5th got her up to 181 mph :eek:
2nd pull 437.66 rwhp & 494.97 rwtq ran her in 4th
3rd pull 440.03 rwhp & 495.03 rwtq ran her in 4th

I am happy with the rwtq numbers, but thought the rwhp would be a little higher around 450 rwhp. Just wanted some feed back from you guys. I saw some thread saying that stockers should be right around 406 to 420, but I read someone elses thread that said that their stocker pulled 453 rwhp is that possible?

Are those SAE corrected #`s? I never ran mine stock.With the Magnaflow w/ cats ,Gibson headers I did 448 and 505.

I haven`t run since the VEC2 tuning,cat delete, 3" mids,TB,Volant .I expect 500 RWHP and some more torque maybe.

They used STD #'s for the Dyno.

Not too bad...may be on the low side by about 10HP, torque is about right for those mods.

Next mod should be cat delete or mids w/HF cats ;)

Looks Good I'd be happy with those #'s :D

STD values will read higher than SAE values, by about by 10-15 RWHP in that HP range.
Ask them for the SAE graph as you'll be able to compare results better, now and later.
The SAE values have a better correction factor for altitude, pressure and humidity.
All they have to do is click the mouse to select SAE.

ThankSS Sean.Mine were SAE #`s.
