So whats your horsepower goal? 600 wheel? 1000's will get you to about 500-550 to the flywheel

Oh hell yes e85 will chew through fuel

Then I'll be able to crank that timing up and not worry about stock pistons failing. Mainly the ring lands. 20psi and 9000rpms all day.

I decided to upgrade injectors. I am going to need them anyways. Here is some useful info about the injectors. Larger injectors above 900cc are more challenging to tune at idle and cruise compared to the smaller injectors. The graph depicts the range in which the larger injectors pulse widths are no longer linear below the cruise point and the smaller injectors are ok from idle on up. Good to know. So I'll have fun tuning these in. Cheers!

What is your opinion on these FIC injectors?
What size injectors are you using?

I've not yet installed mine, I'll probably do so tomorrow, so I'll keep you posted, but as technology goes, the atomization is much better and high impedance is better now a days

I installed my FIC injectors. I can tell right away that they are more quality than the previous. I haven't drove yet. But the idle is great.

Night and day difference with the FIC injectors. Especially on idle and part throttle. Thanks for your help forevertrj.

So! got my injectors in finally, set up everything and now my fuel tables have a value of 1 for idle manifold pressure and 3 for -20.9 inch of Hg, I've got my fuel rail set to 43.5 PSI to make my injectors behave like 906cc/min for the deadtimes and when I went out for a rip the tunes still rich but not by that much, the issue just seems to be when idling I'm guessing I'll upload the tune any any help would be appreciated, basically if my fuel values for non vtec tables are above 5 I go super lean, and then the wideband rolls over to a rich missfire and shows a lean condition, basically I can't take the fuel value any lower and even if i change the overall trim to lower it even more to bring the fuel values in the tables back up that doesn't work any help from spunkster would be awesome! I'll probably have to repost
