Are these numbers normal?

I took my car in to tick performance the other day to install my kooks longtubes and kooks highflow catted connector pipe.. I figured since PCM for less is in the same building with them I would do some before and after on the dyno.. my car put down 370hp bone stock.. then we installed the longtubes and high flows and put her on the dyno again.. we let the engine heat up to normal operating temps and we got 403HP and 402 TQ!.. to be honest I was only hoping to see about 385-390 other than the LT and highflows the car is bone stock no cai no tune no catback... are these normal numbers or should I be very proud of my baby?

Those a re pretty good numbers .. there are a lot of variables to dynos (so hard to say about if your stock numbers are good etc .. as you could take it to a different dyno and dyno less or more) so you can say with your mods you picked up over 30hp without a tune .. give her a tune and you will get more as well

I'd say for only have the longtubes and high flow cats, that is a pretty good gain.

Bone stock my car dyno'd 370whp. Today I got it tuned with my ARH longtubes, catted X, Magnaflow axle back, and Fastlane CAI. In 101* weather (120* intake temps!) and the computer pulling 3* timing it put down 403/410. So I'd say yours is right in line!

My LS3 put down 368 bone stock and 1200 miles on the odo. After CAI, Tune, Long Tubes, high flow cat, cat back - 405. Looks to be about right, granted I'm no performance expert, but it seems inline with what I experienced. Would be interested to see what you gain with a tune.
