I second the bigger injectors.
Add a front mount. Doesn't have to be the huge one that most people use from Kinetic. They make smaller ones too, but if you can afford it that big one is a monster.
Weight reduction is a huge factor as well. Not sure how far along that path you are willing to go, but a CF hood, light battery, light wheels, and aluminum front and rear bumpers are a good start. If you are willing to strip the interior, you can save alot of weight. Did you do a light flywheel when you put in the ACT? Taller 1st gear in the tranny?
Are you traction limited yet? If so, some stickier tires?
I suggest getting rid of the VPC if you aren't able to use it.
Get an Eprom with a good chip with stutter box and no lift to shift along with some good timing and fuel tweaks, and that along with the SAFC should be good. Of course if you can afford it, get DSMLink.
Get a good adjustable fuel pressure regulator if you don't have it already.
If you had an Evo16g, I'd say leave that alone, but maybe with just the 16G, well you might want to go bigger. And if you are going fmic, you might as well get the pipes built for the different turbo while you are at it.
also, what gas are you running? 91? 94? C-16? I bet you could run more boost on your setup.
Also you can try water injection, then I KNOW you can run more boost
I'm currently running 20psi on my 14b and Jason G is running over that on his.
Good luck and keep us posted.
