[QUOTE="Devman, post: 15500979, member: 183850"] Hey guys thanx fort all your input sofar it is greatly appreciated especially you Pro60modman. I have access to both the advantage 3 software and the sniper commando software which I kinda like better. Sofar wat I have done is calculate the difference in area between my old sct maf housing I.D.(3.5) and the area in the jlt high boost I.D. right by the maf sensor which is 4.25 and I think I came up with 1.395, i forget exactly but I have it on my computer and I multiplied that to all the air flow values in the maf transfer function and now it idles just right it's not bouncing around or hunting anymore and it's dropping pretty nicely between gears, however it's staying up around 1100 and when the car is rolling and in neuch it stays at like 1500 to 1600 and I'm wondering if I shuld adjust iac duty cycle for neutral and drive for that. Also when I get to about 3200 to 3500 it starts to run way rich because like you said most tuners can make power easy but when it comes to drivability, low end and idle they don't care cuz they just wanna get u out the door and take ur 500 to a 1000 dollars and have u come bak and do it again.
