Went to the dyno today and got tuned. LQ4, 3.1 pulley @ 6psi, GT2-3 cam, and TOG headers. 19 degrees of total timing. 1 degree netted 10hp!
Im going to have to work out a few issues.
The injectors are at 100% duty cycle by 6000rpm. Going to have to make sure the inline pump will supply enough fuel that the 60's are going to need. I want to go to a 2.9 pulley. Going to install the Metco 100mm pulleys. Im only averaging 5 psi and 6-6.5 when the trans shifts, thinking it is belt slip. The crank pulley is pinned.
Numbers are;
448 rwhp
453 rwtq
I will post a dyno graph when the tuner emails me it.

Damn! I'm really gonna have to pulley down a little now! Excellent Jason! The GT2-3 shines!
Are you going to run w/ me at Infineon next Weds?

You guys are putting out some nice HP numbers. Thats it, you made up my mind, cam will be ordered this week!
Not sure why, maybe the higher compression but my truck is putting out 470tq on stock cam on a lq9.
Congrats on the good numbers.
Where you ordering metco pulleys from?

What is dynapak?
It is a chassis dynamometer, clicky here (http://www.dynapack.com/dynapack.html) The load presented on this dyno is more than the street would actually. Pretty cool setup.
Sorry for the HiJack Jason... :(

Ok, so it would be comparable to a mustang dyno. Just trying to see who is showing higher numbers because of a dynojet or similar.

Damn, good numbers...I'm exceited to get mine dynoed now, should be interesteing to see if we can tell a difference between my cam and the LPE cam. Maybe another month or so and I'll be ready for the dyno.

I was on a dynojet.
The numbers are okay. 500rwhp is my goal. I think with the 60lb injectors and 3 psi more boost, I may be closer to 475rwhp.
Im kinda confused about the numbers. Mine looks kind of like 5.3 numbers with the hp and tq numbers nearly the same.
Going to the track today, hopefully I will see an improvement there.

Don't be glum! There is nothing wrong with 450hp! Dont forget, you're putting it thru the 4L80E which sucks more juice than the 4L60's or so I understand. Get some more fuel flowing and add a few lbs and be happy! (better hurry before I do the same!)

question for you guys running the GT2-3....how hard was the tuning for that cam? do you see any misfires now that you have that cam? any idle issues? any weird stuff happen after you did it?

No lope at idle, idles like stock. 2 tuners have tuned the truck and both said the cam extremely easy to tune for. I have not had any misfires in the last 8 months I have had the cam in both the 5.3 and 6.0.
