Also I was looking at a speed unlimited/kirban 5005 billet aluminum adj for on Amazon. It is a good upgrade and will fit directly to stock rail . and can be used if I upgrade rail with one on this site ??

Set it to stock (39psi with the vacuum line pulled from the FPR) and adjust from there if the AFR at WOT isn't where you want it. Fuel pressure makes "global" changes though (meaning it adds or removes fuel to the engine under all conditions, not just WOT) so you have to make compromises with the stock ECU like allowing it to be "too rich" at boost onset so it's still safe at redline.

And basically that is at 10.5 on turbo coupe correct cause that were mine always was before problems started from tail pipe touching fuel tank and boiling fuel on way to colorado. So I'll put new walbro pump in and get the fuel presure at full boost before putting kirban fpr in. I don't want to band aid it. It runs leaner since that trip. Its fifteen roughly at idle and 11.5 twelve at wot.

11.5 is "ideal" but 12.0 is probably OK at stockish boost levels. It should be 14.7ish at idle/cruise.

I put in the walbro 255 high pressure pump . pinging seems to be gone and I am pretty sure I am at 11 .3 or so at wide open throttle. So far so good .I have the kirban fpr but will wait to put in after 100% sure isues are fixed with air fuel rstio. Haven't really driven far cause car isn't insured yet .
