Getting started on some tuning, this was hi 10 low 11 ar with 8-12 degrees timing on 10-12 psi and its shifting eairly most of the pull was third gear. full waight with passenger and on my 20s. I think its off to a good start cause its already running better then my ls1 I think.

Was that one solid gear? Or was the a shift around 60mph?

Looks like the 3600 converter works well.

 

WTF , that thing just moves what gear was that ? ....

 

It started in 2 but shifted into thrid almost right away around 60, I put new rings and bearings in the engine so I didnt want to rev to high till it had some more miles on it, 5500 shift points witch isnt vary fast with a 3600 stall lol, I think it will act much better with 6500-6600 shift points.

 

That run was actually about 10.0 afr and 8-9.5 degrees timing.

 

Damn that thing runs well.. Any numbers or times with that set up?

 

Looking good for your base tuning, and break in period.

 

Pretty much got the thing together 2 days ago so no times on it yet, track opens in march and ill get some times and see how she acts, I think the 4.56s need to be changed for atleast 4.10s maybe 3.73s yet. Plus its the first boost tune my bro has ever done so once its all nailed done im sure she will come alive some more. Im just running a 255 pump with #44 injectors right now, plans are #80 with twin pumps and 15-18 psi on the corn juice.

 

That bitch pulls hard! I wouldn't change anything just yet. Work on the tune and get it to the track, so when you do make changes you can be sure they helped instead of hurt.

 

Yep thats what I was going to do, I guess I should say once its all setup good and kinks worked out I want to end up with e85 18psi. Once the tune is all done I think the next thing on the list is 3.73 gears, these 4.56s dont seem to lug the engine much at all till third gear and first is nothing but a tire roast.
