logger as in the obd2 diagnostic test? i just had my motor taken apart and they said everything looked good.

i looked at them today and they looked good maybe a little lean since there was some white on the bottom what would cause this my car was running rich the first two weeks.

i havent noticed a difference really but i havent been getting on it im buying a safc if i dont sell it soon i just dont have the money right now

ya i havent been running it hard because im trying to sell it i have an AC fuel pressure regulator i got it from my shop i go to.

ya i know that one lol my dad found that out the hard way today haha

its never been this hot before at the tip i dont have any fuel controller right now so it should be running rich if im correct. i have noticed a big difference in temp since when i first put them in and now

I just put 550cc injectors with the walbro 255 and a fuel pressure regulator set at 40 psi at base and my exhuast is very hot. I have had them in for about 2 weeks now and today i went to feel my exhaust and it was burning hot. I read its from running to lean. what could be my problem here?
