I agree dyno numbers are just smoke and mirrors it's all about the seat of the pants feel..... Car is either fast or not, who cares what the dyno says, but the sheet does look off...... Never seen a curve like that.....

I have never seen a dyno graph look like that.

That combo should make 420/400 on a Mustang Dyno all day long.

Martin at Tick Performance helped piece everything together for this build. He estimated the car would put down about 440-450 RWHP when all said and done.
Might be worth making the drive to Edmonton or Calgary to have it run on a dyno. Both cities have a few good options for LS cars.

Looks like the closest DynoJet is in Saskatoon if you're interested, atleast you can verify your results.

I have a similar combo on my LS2 with CNC'ed factory heads and a ported intake and TB. Put 470 to the rollers. Something is off because that graph looks odd.

The CTS-V did not get an auto until '09, which was an LSA powerplant at that point. He will have had the T-56, unless he's one of the very, very few to auto swap his 1st gen.

Well, whatever the problem was, apparently it wasn't bad enough for Karl to check back into this thread to follow up on the various comments and suggestions.

I always find that odd.
