i dont have hondata, and theres alot of other 12 and 13 second hondas that dont run hondata, but hondata is an awesome tool and you can get alot better results with hondata then just an afc, hell yea an lsd will help, i wish i could buy a quaife so i could stop breaking differentials and start busting axles, trannies get expensive after a while, im on my third tranny, thats why i stopped runnning on slicks with a stock open diff, but then again, my buddies running 11.7's on a stock diff on slicks, his clutch is a street disk which is helping him not break shit, they have alot more forgiveness than my 6 puck.....
