new update..still haven't put the temp probe in but will this week I hope. I did order 80lb injectors and have a 100mm maf. So we are going to try a retune with the new maf since I already exceeded the factory limits and install the injectors and LOWER the base fuel pressure and see what happens..Temp probe first

Well car has been sitting for a year got me a jeep wrangler so been having fun modding and 4 wheeling with that. Anyways I decided to wipe the dust off and try again. I got me a new fuel tank as this is the only thing I haven't changed. All I have left to do is swap over the secondary lines into the new one and install the rear and TT. Ill update when I finish I been taking my sweet time since I started last month. In all honesty this could all be done in a day. but mehh.

I resolved my own fuel pressure issues today. I'm not sure which one was the primary culprit, but I swapped out my racetronix walbro for an lpe walbro and replaced the fuel filter. My two least favorite jobs.
Rail psi went from 55-58 to 62-65.
After a test run, absolutely no loss of pressure at any rpm.
Now if I can get the methanol kit working right I can tune the car for real.
