Hot weather or not, if you are detonating at 12 degrees of timing with premium gas you have a problem. It sounds to me that you are running too lean. What is your fuel pressure at WOT? If you have a fuel pressure gauge on the schrader valve you won't know. Just winging the throttle won't tell you. You need to read the fuel pressure under load, all the way up the rpm scale.
With you combo 24 lb injectors are not yet necessary. Probably 32 psi at WOT is all you need. Also your stock fuel pump may be failing. |
