I am only running 8psi, but I know if I get a boost contorller I may run into problems quickly. I am sure Rice will be on here soon telling me to go with water injection. but i am not sure how much it would benfit on so low of boost and a stock TMIC with poor air flow.
You don't quite understand AI, do you?

If co$t is a variable that defines your choices then up grading your heat exchanger is the easiest path. Given what you are doing and planning an upgraded intercooler is the way.

I suggest you do the following.

Box that intercooler, turn it into a water to air set up. Buy a cheap ass water pump and control, and a small front mounted heat exchanger and some hoses, this will solve ALL of you temperature problems and cover you to triple the power you use now. It is one of the best options available which most people discount, I have done it many times with great results.
Interesting.... what's that saying about thinking alike? This is exactely what I am in the process of doing with the 'vert....

So. . . .Having someone turn a Air to air into a air to water is better then buying one that was build from the start to have that function? That makes no logical sense to me. I have no Idea how you plan for me to box my intercooler. I would guess the best way to do it would to TIG weld it. JB weld would fail. If I weld that intercooler I should pressure test it. I do not have a welder down here. It seems like a DIY job that I could do would not be very good. I am sure having someone to box my intercooler would not be cheap, unless I want cheap work. I do have a spare, so I could ship that one off.

And no I have very 1st hand knowledge about WI and AI, I thought I stated that I found it a bit confusing.
