I installed my gauges today, fuel boot and pyro and after it was all hooked up and I was testing it the black smoke not in short suply, it never did this before the install. it boosted 21psi and ran at 900F, i did nothing but put the gauges in and have no idea what made it do that. it runs great.

 

I would say a boost leak with excessive black smoke as you describe, however with 21 psi that kinda gets ruled out...Can't really think of anything else at the moment, have you by any chance messed with the Superchip lately? Perhaps the chip is malfunctioning? Maybe others will chime in with more input...

 

the only thing thats been goin on is the body control modual going crazy but i dont think that would have anything to do with it. maybe im wrong though
