Dyno tune time: Make a Guess Hey Guys, my car is going down to East Side to get tuned on Friday. What I would like is guess and predictions on the power out put. I will provide as much info as I can based on what I have and a previous dyno pull.
The Car:
2002 Pontiac Trans-Am (NON-WS.6)
SLP Flow Pack (Lid, Smooth bellow, Sheet metal Duct, and SLP Blackwing filter)
T-56 Six Speed w/ Billet Steel Flywheel
3" Steel DriveShaft
Moser 12 Bolt w/ 4.10 and Tru-trac diff
Dynatech SuperMaxx Header kit w/ Their Highflow CAT
Corsa Cat back exhaust
Stock Intake Manifold (LS6)
Untouched TB
Stock Rockers
Stock Crank Pulley
Stock Waterpump
NGFK TR-55 Plugs, gapped to stock, z06 plug wires
Free Mods: Descreened MAF and Free Ram Air mod
Coolant still runs through the TB
Currently Untuned
On the previous dyno pull and at that time it was BONE stock except for the Flow Pack and a stock driveline. It was on a Super Flow Dyno.
324 RWHP
346 RWTQ
I am having Eastside do 2-3 pulls to show the untuned power w/ the new bolt ons and driveline
Then after that, tune and re-pull
So if you want to guess list it like this
Un-tuned RWHP:
Un-tuned RWTQ:
Tuned RWHP:
Tuned RWTQ:
My Guess
Un-tuned RWHP: 335 hp
Un-tuned RWTQ: 355 tq
Tuned RWHP: 345 hp
Tuned RWTQ: 360 tq

We had a good friend of mine change and he saw with a H/C car a decent loss but it wasnt a "clean" swap so there is some variation
Well since it's a "non-WS6", I'm going with 310/290.....
Honestly - I'm gonna guess untuned about the same as previous dyno. The gain from the full exhaust will get washed by the heavy driveshaft, 12-bolt and gears.
After the tune, 335/350. If you have a STRONG car, maybe 340rwhp, but I wouldn't expect it unless that stock tune is really killing you.
I think you are viewing things optimistically, but I'm hoping for the best for you.
