Thought you'll might find this funny. While predicting the power output of my 350 TBI, LT1 cam, ported "193s"(did it in my garage as an experiment), Ultimate TBI mods, and 350 injectors @ 15.5 psi. Here is what the comments had to say.

"Throttle body TOO small, Injectors Too small, Poor A/F mixture distribution, detonation likely".

This engine will be making around 285 hp and 350 ft/lbs according to EA. I found that with 454 injectors @ 15.5 psi that it would still take almost 80% duty cycle to feed it???

Its cool that this program will give you somewhat of a guess on the duty cycle and pulse width that will be needed.

Oh yeah I also have their fuel economy predicter and it says 22 mpg @ 70.4 mph and 1,950 rpm. Slow down to 65 and 24.7 mpg @ 65.7 and 1,850 rpm. Drive 75 and 20.8 mpg @ 75.2 mph and 2,150 rpm. That is with the A/C on med on a 100* day, the alternator putting out 40 amps, a clutch fan, 2,200 rpm converter w/ lockup starting in 3rd in a 700r4 w/ 3.42s in the rear in place of 3.08s. TBIs rock for fuel economy.

That's pretty cool that it will do all that. I've been looking at buying engine dyno software lately, and am leaning toward the EA stuff. What does everyone recommend here?

Crazy how even the engine building software thinks that the TBI sucks. Although I think that it can be worked around.
