I still run the old tunes stacked with a smarty I find this to b the best,,, with out the smarty I dont care if its a 1000 tune there is a stumble around 2800 give or take a few and up free rev or normal cruz .. But for some crazy reason the smarty clears this up and takes the RPMS to 4+ now I dont understand if the box puts out so much fuel to cause a stumble why do I add more fuel to smooth it out ?????
Quad ,,,,mike the VP monster guy has your box and is going to try it once he's back and running
Not to b bashing the box all the time I find it to b the best I'v tried so far but I'm not a fan of stacking either ,,but I dont see how its to much fuel causing the sputter , I'v got some HUGE injectors that u cant even put a HP # on and theres no stumble usen them and say any other box out there
Now is it possible the box may drain the pump on a certain injection time were it didnt have enough fuel to fire then thats were the stumble comes in at the higher RPMS ???? But I dont see this happing on the MVP44
