UPDATE:

First I fixed the fuel issue with steel braided line and a bunch of aircraft fittings from the hot rod shop. Should hold up great now. So recently I have been tweaking the suspension of the car to only find some issues. I lowered the front and the rear. Toed the front in, and cambered a little bit more to see what its like. First thoughts, the car was squirrely o nthe road, tracked weird, turned great, the camber in the front made the tires inside wall the only thing on the pavement, the dead torsion bar setup I have wobbles in and out where the a arm rod fits. So I am going to either build a straight rod to replace the springs inside their or just shim the arms apart so there is no wobble. This could be the reason for some of my high speed scariness in a straight line.

So to fix the camber, take the car to less schwab for a toe alignment, and then adjust the drop accordingly, and fix the wobble issue soon.

Other than that minor issues have been occurring. I noticed when I filled up my methanol tank the line running to the injector on the manifold was leaking... I'll fiddle with that to get that fixed. I want to lower my idle a little bit from 1300 and lean the car out a bunch across the map. Will mess up whatever tuning I have done but it might get better gas mileage then etc. I undercoated the chassis again and might drop the engine to replace the throw-out bearing as it makes a weird noise after only 1200 miles... More to come

UPDATE:

The first shop my car ever went to was Tire factory to get the toe caster and camber aligned. After fiddling with the car for the past week to get it better I gave up. The tire gguy said my home adjustments were close enough without needing adjustment except toe was bad and the rear is super cambered but that's whatever cause that's just what bugs do with a drop.

I sat down and looked over every single aspect of my map and decided a complete overhaul and drastic tuning methods is required to see major differences before I try a tuner and spend big money fixing my issues... SO I had my dad drive while I dropped my opt mix trim function to richen or lean the entire map all at once. Changed all my load and idle values updated my timing and air intake temp map and water map. Through lots of black lines on the pavement and drifting on the Boeing freeway entrance it is surprisingly dialed the hell in for a day of bashing. afr's on cruise, idle, freeway drive etc are all at high 13's to high 14's. Boost goes from 12.5 on 4 lbs of boost to 11.8 ish on 12 lbs which is fine by me. Gas mileage should increase and power jumped a ton. My timing map increased to off the top of my head I think positive 16 ish on boost with full meth spray. No knocking whatsoever even when bogging up a hill in a high gear so its completely fine and could even go more with a proper tuner and a dyno setup. After blowing up the rear rotor's spark plugs on day one of tuning I bought some simple br7es ngk plugs for my engine. The thread length etc all matched except the thin walled socket will be required if I plan to run them continuously in the future. Checked the plugs today and they are cocoa brown. So it is liking everything so far.

My new fuel setup works like a charm also. And my Banzai Racing cosmo oil pan brace took a little time to put in but I squished in some Hondabond & some gasket material between my engine and the semi warped oil pan lip and the whole setup hasn't leaked one bit!

Now to get the little bugs out with some finer tuning and to get a dang go pro camera one day...
