Could I have the wrong injectors?

[genxxxracer]

I have been trying to tune my setup with the s-afc. My egt's arent reading over 500C and the timing isnt getting pulled. Nothing changes when you set it to -40 or -50. I think maybe the 720's are too big possibly. Is there anything else I should pay attention to. Heres my mods.

2.5inch greddy evo cat back, greddy upper and lower intercooler piping with type-s blow off valve, S-AFC, 720cc injectors, frank 2 turbo, 3 inch downpipe to straitpipe, ported exhaust manifold, ported 02 with dumptube, pocketlogger,mbc, custom 3inch intake with k&N, boost gauge, egt gauge

A lot of the fast guys don't pay attention to EGT's...including me, but I'm not fast..yet..Anyway, you want to be concerned about your knock retard and timing...Focus on these two things rather than EGT and see what happens....
