im gonna take a hit if i get the bigger intake and TB? what do you think stay stock with those parts?
Check out some.of the dynos from others who.have switched from.oem to the gt350 IM. You're trading some low end grunt for top end hp. Obviously, that's going to.change with the 90mm tb. All depends on which direction you want to go with everything.
Not sure of the stoich AFR the Dyno WB is set to but the reason you may not have seen the timing you wanted is because its on the lean side of where the WOT lambda should be. could be anywhere from .90 lambda to .86 lambda depending on the WB settings. Not saying it is bad lean, but usually if its slightly richer you can run a bit more timing. You will make more power running it leaner with less timing as you are and thats what you are probably after.
It actually was running a little rich at WOT, but the horrid gas forced us to pull back the timing. It was only after pulling back the timing that we had to go with the leaner mix.
Cali 91 sucks I did a ton of remote street and dyno tunes on cars out there and they always had to run 3-4* less timing than I would normally use. PE lambda I kept same as usual.
Dyno I would suspect. Torque that high is very rare on a coyote and guys making it are usually 440whp on the stock manifold on E-85.
