mrpositraction said:I have been bouncing between 93 and 91 octane. Depending were I am at. In St. Louis (where I work) we have 93 every where, in Columbia (where I live on the weekend) we only have 91.
narongc73 said:Really? I thought 6psi requires 94+ without the intercooler?
raykrv6a said:92-94 required for 6 psi non-intercooled.
You could also run a tune with less timing to run 91 if that's all you had.
mrpositraction said:Wow, my bad. I thought it was 6 psi and 91 octane but it is 5 psi for 91 octane. Well I have went through 3 tanks now and had zero detonation. I have looked at KB sight they support what you say; 92-94 octane for 6 psi non-intercooled and 9 psi intercooled. I have the chip from Kenne Bell and have had no problems.
I wouldn't worry about it unless your hearing detonation. You have a choice with detonation. Either run less psi, 5 vs 6, or run less timing. Imrpositraction said:Wow, my bad.
