hey guys im FINALLY going to get my truck dyno tuned on monday. I have a stock 5.3, 4l80e, zo6 cam and springs, and 241 heads which should bring compression down to 9.1 or 9.2-1. custom front mount with mp70 turbo, intercooled. what do you think would be a good boost/timing combo? i want to run 10 lbs and im debating e85(105 octane). I can get it for $2.79 a gal, and prem is 3.99+. any guess on the numbers? thanks

you running meth? I would be safe and sneek up on it. Maybe start around 15* and add from there. A thing to remember, my truck will handle alot more timing on the dyno than it will on the street because of engine loading. There is alot less engine load on a chassis dyno. Besure when your done to do some actual road testing to make sure it won't knock.

thats why if you do tune it on a dyno do it on a mustang dyno with an eddy current loader to put the actual load on the vehicle..loads are variable depending on vehicle
