so it would be good to get it for my xcal 2 and get the race tune 91/93 from bama so does that mean i only use 91 on my car and not 87 cause the highest here is also 91 im in the so cal area also

landon.moss

yup...only use the octane your tune is set for...on hi-po motors it will cause pinging, and supposedly doing a 91 tune and running lower octane will cause pinging as well (not good)

kaponelb

so if i go with 91 i have to use 91 all the time so whats the best tune out there for me

landon.moss

that is correct....guess it depends what kind of/how much driving you do/how much you wanna spend on gas - i thought i read that some peeps with the economy tune didn't notice a huge difference from the race tune...i'm pry wrong on that one t's pry the torque tune compared to race tune is minimal dif

i dont drive my car much so i dont think the 91 would be a big problem so what would be the best tune for me

kaponelb

sancho805 what tune do you have on ur mustang

kaponelb

whats the difference for
91 torque
91 race
91 perfomance

someone told me i should at least get a 87 performance whats that for but wich 91 tune should i go with whats the difference between all of them

The difference in all of these tunes is pretty much timing, fuel, transmission, and throttle settings.

Each tune (or tuner) designs tunes to perform specific tasks. A torque tune provides more low down torque, but probably less HP up top. A race tune is meant for the track, not daily driving. A performance tune is a good all around tune for daily driving.

The best answer for you, is to decide what you want out of your car, pick the tuner you want, call them, tell them what you're looking for, and have them suggest the best tune(s) to suit your needs.

Actually, the best answer (if you can afford it), is to find a good tuner and have your car custom dyno tuned for your specific needs.

i have a scal2 i tihink ima go with the 91 performance just need that extra power on the streets not track stuff for me and i dont need torque

kaponelb
