From what I gathered, it's all in the tuning. But that will all be in the dyno places hands for me. I have the softwear to go with the portfueler and I'm also having an EGT probe and autometer guage to help them with tuning. A lot of help I recieved from etx from this board about my fuel system and whether it can handle 20psi and doing some research it seems that the 4g63 engines can handle that all day. The evo has 20psi stock it seems. I found the posts that said what is needed for 18psi but the portfueler never came out during those posts so i'm not sure how it compares.

I def. have a lot to learn but I'm doing all the research I can do but as always I figured it wouldn't hurt to ask.

Also with my rebuilt kit I am using the MLS metal headgasket and I have a stage 3 clutch from titan motorsports as well. Just looking for any info I can get, what would I need to handle 20psi if not this?
