some test results:EZ "alone" on level 3-noticable decrease in lag off the line( im assuming the timing adv. is whats helping)still not as much of a decrease as with the boxes "stacked". and SHANTI,here's one for you! EZ alone level 3-at "WOT" boost was a max of 30 lbs. (???)and egt's were 1000 deg. max. what caused the boost to lower?? shouldn't i still get a higher reading due the J-HOOK ?? what really excites me is to get to WOT with the EZ and then "IGNITE" the POWER MAX3 (pre-set to level 9,,of course)and hold the h*ll on !!! running the ez alone with the transmission upgrades feels pretty good. the ez alone adds some nice throttle response but the pmx3 alone is much much more. im definately not bashing the ez in any way. the ez alone just ain't enough for me,,but "stacking" it onto my pmx3 puts the icing on the cake!! im gonna due some towing with the combo and will probably leave the pmx off and see how the ez does. it might be worth buying it to use for towing and everyday use and turn the after-burner(pmx3)on when needed. as far as getting the back tires to burn off the line as before the transmission upgrades with the pmx3 i dont think its gonna happen. i do definately get them chirping now though with the "STACKED" boxes. i believe if it were a single rear wheel truck it would do some serious tire smokin. thank you BILL K. for sending me the ez to try before deciding to buy. really,,how many peolple out there would actually let you try the stuff out like BILL did me. i haven't hooked up the t/c saver yet but will do so before my camping trip. i'll be callin ya after that. sorry for the long post,,just thought someone might gain something from my findings.
