I had a bad map sensor that showed 10psi boost when the key was on but truck not running, it would put out a cloud of smoke in neutral when you rapped the throttle, like a 12v and man would it smoke :-laf but I have to drive it every day so I fixed it. Unplug your map sensor plug at the block and leave the other plug of the Comp hooked up, gooood smoke but real touchy when driving. Thats the way to get smoke out although not very feasable but I have the bad map sensor the "smoker series" on sale now for $199. 99 to a lucky soul who really needs the SOOT!!!
