    Default leaning out tune?

    Car has alot of surging unless there is a large load on the engine witch im trying to tune out some. Also seem VERY rich at idle. Whats the best way to try to lean it out under light load? Ive got tunerpro rt setup.
    Started with a mail order tune witch obviously I knew would need some adjusting, Thanks.

    ve master. lower ve table by 5% in those cells, also lower maf table 1 and 2 by 5%. what's your iac set at? you can also adjust the spark correction over/under for idle rpm too to smooth it out. stock it swings like 10 degrees for a 50 or 100 rpm change which is large. iac at hot idle between 30-50 counts. tps to .57. what throttle body?

    no problem. also what cam are you running and what is your hot idle set to? my hotcam actually surged alot until I raised the idle to 850. my le cams always like 900.

    I believe its 750 and it does seem a little low.
    Cam is a LE spec Lunati 224/231
    Think I should just try raising the idle first? Whats funny is there is NO surging until it hits closed loop, then its like bucking so bad at parking lot speed it almost makes it feel like its missing or running out of gas lol.

    way too low. bring it up to atleast 850. is your car auto or stick? auto prolly 875ish with stock style stall. then set your iac and tps up. then start tuning ve, timing, etc

    @MoeHorsePower My car has MAF and you did mail order, I text you the other day but I know your busy.
    I do have my shop desktop computer setup to where I can reflash my PCM now though so I wont have to mail it anymore.
