If I remember right it was number 3. I took all the timing out that I could, you can't add fuel so as far as i know that was all I could do.
I did try the other programs with the same luck.
Like I said for a somewhat stock truck I bet it's fine But in my case with my mods it was just not going to work.

With your mods you should be pretty close with that package.

I think they listed everything at 58hp.
I would have to dig up my notes to check that.

to change fuel with the truck tuner you go into the injector sizing and lower the injector size. by lowering the injector size without actually changing the injectors, it will add more fuel. even though you were taking timing away, it just wasn't enough to compensate for the lean condition you had. the bigger TB added more air, which in turn leaned it out more. next time, just call vinci if you can't get answers from crane. vinci and crane have been working together since the 60s. vinci did most of the R&D with crane on the tuner.

If it were me I wouldn't go with such a large split in your truck with the small cubes. It will make the bottom end lack a little. Maybe a 220/224 on a 112. With those kind of lift numbers on that cam though, it will survive with the ls6 springs. That would be a lot cheaper spring and just fine for that cam. Other cams may need more spring thoguh.

Good info! I was going to call VHP tomorrow and ask that.

Installed my Crane tune this weekend and it seems to pull pretty strong. I'll get a chance to test it's cam tuning abilities in the next month too.

For us cam dummies (IE-me) when you say a "large split" are you refering to the LSA?

duration.

he was referring to the intake duration @ .05 216 and the exhaust @ .05 224

seen as 216/224 .551 lift on a 115lsa

you'll hear people describe the lsa being wide, or tight.

tight is lower numerically (109lsa)
wide higher numerically (115 for ex.)

What he said ... big splits like that are nice if you have a crappy exhaust. It will compensate for the lack of exhaust.
