The "Smoke Switch" forum guys had Axcelerated Motorsports up there at some parking lot Saturday for dyno runs because they are all scared to go to a show somewhere and dyno in front of anyone but themselves.I am waiting for the results to be sent to me as none of them over there want to post up how they did,well one did anyway.
You want to spend some time dynoing then the closest place to you is John Anderson's "Little Power Shop" up in Bradford,PA about an hour North of you.They have a Superflow jet that many have been on that will give you numbers to help you tune with.What tuner are you using right now,SSR or Quadzilla Junk?.I do not think 75% over Exergy's will get you into the high 700's consistently but anything is possible in good air with the right tune.CAC will help cool the air charge some but do not expect big power increases on a dyno from a swap of them.
If your using SSR then you need to spend some time with it strapped down to see what your truck wants.I had hours in mine to get close and find a reasonable place to start with to build on.If this was your first strap of the truck,keep working it will come but do not expect it to happen overnight.If you need a hand,drop me a note and I will do what I can to help..........Andy
