Both have about the same rating and the HHR has a much better stock intake than we do. BartSS's HHR made 286 whp and 293 wrtq on that same dyno and he has stage tune plus mods. I believe he had DP, CB, IC and CPs. Every dyno is different though and I wonder what a stock SS/TC makes on that dyno you used.

I'm sure those #'s(BartSS) are correct but I seem to recall him having a tune on top of the Stg kit(at this point).
I had the stage kit installed and a CIA dp(catted w/cutout)installed within a mile of the dealership so actual gains are guesswork although eyeballing the two the differences are apparent even with the(hi-flo)cat. When I'm able to uncork the cutout the cat and OEM exhaust won't be a factor; if I ever get to a dyno I'll test it both ways.
Dyno noob question: traction control off?

I dunno if I'll re-dyno or not, but I have ordered a DP, so if I do choose to re-dyno I will have a good baseline for the addition of a CB before and after a DP.
