i wouldnt worry about the CAI, no gains really... have you looked into an intake manifold spacer?

mine would do that same thing when i put on new intakes and it had a vacuum leak and the IMRC's were disconnected... idk if the newer mustangs have IMRCs but i would check for a vac leak.

when datalogging the fuel pump duty cycle, what is the max percentage it will go up to? 100% or 50%

your mileage will be wrong too, if you drive it w/o putting the tune back in it.

also, does this new revision have the option to cut off the egr or turn off the rear o2s? i was looking and could not find it.

you have to load it to the computer using cmr, save it the file where you can find it, then attach the file to an email and send it to mike or whoever. you have to have two cords, a power source and another cord. its on the intsructions i believe. just read it. go to support, then downloads.

you could just have one made somewhere near you that does designs, tags, shirts, etc...

ok so i tried to log the gas acceleration wot but it would say selection not compatible with vehicle??? what does that mean, i tried the gas driveability and it worked.

i have 3.73 gears, should i change them to 4.10 to be faster??? my friends mustang has 3.73 and diablo tune took me like 3 cars b4 i got tune, was it the tune or the gears??

if you change, let me get them gears 8) ....but 4.10s will help better off the line, if you get traction, but will limit ...

my 08 sierra denali is doing the exact same thing described....it gets a surge about 60mph when going up hill...about 1600rpm when you are just barely giving it a bit more gas to keep the speed the same... the rpm guage fluctuates and feels almost like it's cutting out like a bad plug...other wise ...

you should be able to go in there and change each shift, 1-2 2-3 and so on, to its own rev limit, or is that what youre talking about.

let me know if you get it.

i meant the one you sent me was the same name as my last one so i didnt know if it installed yours or not....so what does that mean? converter lock....and also resent the log.

i didnt know if it had the right tune because it had the same name as the last one. also im running 93 octane if you need to change something. my 2-3 shift didnt go to the redline, im pretty sure it shifted at 4xxx, why would it do that?

alrighty, replied.
