ok, im stuck, cant figure this out...need help

my fuel cut load is set to 19.88 psi

Well there you go. Raise it to 25psi.

What were you basing your 22.5 and 23psi readings on, gauge or log?

I was basing it on my greddy profec b and guage. they were close. Logs were reading a lot lower...17.5? I would hit peak boost and that's what I was basing it off

Makes sense then. Raise your fuel cut and give it a go.

Update?

i need to get new plugs. install them and then retest. ive been so busy with work havent had a chance. probably order the 7bcep's ngk's or what ever that part number is lol. Chris told me the 8's were to cold for my car and will foul out real easy just driving around

Sorry to hear SIn still running the purple beast?

It depends on how often you get them "hot," I run an ngk heat range 9 non-projected tip plug all the time and only had an issue once and it was a road trip (4+ hours highway driving). I also drive aggressively though.

I used to daily drive non-resistor 9's with a TD04 pump gas car. :dontknow2:

Lowered the fp on e85 then spun a bearing. Coincidence? ...
