Dyno results with new PRC heads & fresh tune

Just got back from Dynolab with the new numbers.

With the converter locked it put down 430 rwhp & 391 rwtq. Unlocked was 402 rwhp & 419 rwtq. Not too shabby considering thats through a high stalled auto & 12 bolt.

Torque wouldve been higher on the unlocked pull but it wasn't possible to get any lower rpm numbers due to the converter flashing.

The new tune made a huge difference (thanks Bille @ Prescribed Power). Feels much stronger & idles great. Now I gotta take it back to the track. High 10s might even be possible when cool weather returns.

I'll probably see it when I come down in the fall!

Thanks! Yeah I've thought about getting LS1Edit or HPTuners but I'll also need to spring for a laptop so it'll be a while.

I have HP tuners for my car. Also have it for 99F-body
All I have to say is HP Tuners put a lot more time in the LS1 Code. There is mucho more parameters you can adjust compared to my L67 code! I am jealous!

Ooohhh boy that sure looks like fun in the making. Great numbers.

Texas speed has a listing on em, where did you get yours? Also, which head did you get, just curious. That thing is going to be wicked.

Damn, those are some great numbers for an A4.
And we know an A4 performs at the track.
Man, I gotta get a tune.

Posted by: EvilLS1

Thanks. Yeah an A4 with 400+ at the wheels should be a beast. I can't wait for cool weather!

Mr.P,
The guys at Texas Speed & Racetech are in business together doing the PRC stuff. Mine were ordered through Racetech. They're the Stage 2.5 (5.3L) heads. I posted some flow numbers on them a while back.. I'll see if I can dig them up later.

{EDIT} Here they are:
