I went to our local tune shop here at Ptuning and they had a open house with food and music and a great turnout but anyway. I dynoed in the summer and I put down 292 and 273 at the wheels at 24psi on a VIII Turbo with a upgraded o2 housing along with all bolt on you can basically have I think.

VIII Turbo 10.5 Single Flapper
3" o2 houseing
3"DP
3"TP
HKS Hi-power Cat back 3"
HKS Super Mega Flow Filter Kit
Hallman MBC "Changing today to EBC"
Comp Cams 272/272
ARP Head Studs
Walboro 255 Fuel Pump
AEM intake Pipe "changeing to JM Fab today"
Forge RS BOV "RECIRCULATED"
ETS FMIC 3.5 Core w/3" UICP and v2 LICP

No port work and no Head or motor work,I put down 329.3awhp 281.7awtq
Dyno Dynamics 0% correction if that makes sense. There was no retuneing involved it was strap down and roll lol it was a way to get customers to the shop and for 3 pulls for 60 bucks it was not bad.

 

did you mix up your horsepower and tq numbers? Its extremely rare to see a 2.0 making more tq than hp.

edit. nevermind, I was looking at the text in your post, you put 381.7awtq, but I see in your sig its 281.7, makes sense, just a type-o

 

Typo but in my sig it was correct it was suppose to be 281 not 381 lol.

 

Great to see man! When you putting on that o2 dump? Would be interested to see how much power you pick up. I made 324/300 VDR dynojet numbers this last weekend on a load based boost tune 91 octane at 24psi. I will post my graph tomorrow just for kicks! Not trying to bust your ***** but you are supposed to post a graph.
