thanks for the reply
i since have added lp and wi to my max, and it works very nice together, i find that with a stack the timing rattle or denotaion is to much, on a dyno it made 575hp with single tune and lp, and 604 with the stack on a 50/50 mix and lp
be prepared for a lot of water consumption, and never run n20 with this setup, i did talk to another member that froze off the intercoller with n20 and wi, cooled the charge to much and ended up doing severe topend damage
i went with the two nozzel system, and it still will bog the motor a bit if not wot, almost to much water it seams, temps are 200degress lower, and take much longer to get up there, boost is up 1 to2 pounds
this picture is what wi did for me on a stock duramax, you can see at 20lbs of boost or 4 seconds into the run, it kicked on and made that type of extra power, with know extra timing noise
