Thanks for the reply you’re always a big help on this tuning stuff. I have deka 60s and was gonna use e85 on it just to protect my hyper pistons in it. I bought a set of used deka 80lbs the other day and I will probably throw those in and sell my 60s. There real deka injectors and not some Chinese fakes. I have installed DeatschWerks fuel pump hardwire upgrade, walbro 450 pump, aeromotive filter, 8an ptfe lines, old downs and fuel rails, 6 an return to a magnafuel pressure regulator, then back to the pump. I figured it would of been easier just to raise the fuel pressure then going through the hassle of putting the 80s then tuning them
