Its not gonna get better than stock injectors man....lol

driveability usually only goes one way....down

As far as fuel mapping is concerned, the KA tune is prettty safe for hi comp. Stock ECU my car will go to 12.5:1 @ ~2500rpms then richen up to 11.5 by 3500ish. Hot days Id see 11.2:1 at redline... Its actually not even a bad fuel map for boost. lol

Timing is the issue ... KA timing curve sucks, especially when you add a header, intake, cams...etc. All you can do is run 93 and slowly turn the timing up till you hear knock at peak torque, then back it off.

Or get it tuned..chip burner, etc.



btw...you remember me? I called you awhile back about the title for the black coupe shell with red vert doors..
