the stock ignition's not strong enough to handle a/f in the 10's efficiently, no wonder

that's the problem right thurrrr.

not sure if you're mailing in your ecu or you're just exhanging tune files but you can just turn the fuel pressure down a little. you don't need base fuel pressure @ 50psi, turn it down to 40-42psi

there's NO reason you should/need to be lower than 11.5 air/fuels

i'm with R.S. in that i tune 99% of cars with a flat line of 12.0:1 maaaaaybe 11.7's by redline just for safety's sake

driftcars maybe 11.7 and 11.5 by redline.

cars where i know the customer's gonna drive like an a-hole and is pushing their internals to the limits then i'll do mid 11's with low 11's up top, but there's no reason your a/f's need to ever touch the 10's

you got bigger injectors, your fuel pressure turned up, and your tuner bumpin 15% more fuel across the map.....don't be scurred sir

get that thing 12.0 a/f and 11.7 up top and call it a day. bam! another 10-15hp, another 10 mpg, no detonation, and no more blowing out spark

that's bout it sir, gl
