i have ran that combo before i got efi live, it did fine the first thing i did do when i go the programmer was put it on the 135hp setting and go took my friends for a ride and limped it as soon as i got into 5th gear under WOT.

i did have a lot of problems with a "soft" over boost code when i was driving above 70mph and it would make the engine go into limp mode to keep it from hurting it self. but i think a newer version of the quad tuner should of taken care of that i think

the month before i got my trans rebuilt i did run it on the 215hp setting all the time, it held good up untill i would try to go WOT and make the 4-5 shift. but i made sure i would let off before it would shift to keep it form limping. but it wont las forever, but it sure as hell is fun if you dont limp the trans. but it will happen eventually even if you dont ever drive crazy all the time

ok that is what i had planned on. Will the head gasket take it? Should i run a boost gauge? I did not get the race on with 215 horse i got the one with 135 horse so will it be ok to run it on the highest setting?

ur head gasket will be fine, those hp ratings are exactly what they are "ratings"

boost wont be too high, but i would get an egt gage first if you can only get one.

I ran the Stealth 2 and Increase Valve both oh my 02 dmax and the tranny did hate life after a few months.. It would limp out at around 75-80 when to the floor.

Yes for sure get a EGT gauge. You will thank yourself once you see how often you hit or get close to that 1350 number!
