Default What Size Is My Super B Single?

I was just wondering in terms of numbers, what is my turbo? What kind if boost numbers should I be shooting for? And how high can I go with the boost? Some reason I only seeing around 30#'s

Bullydog must not be pushing enough fuel. Does it smoke like a banshee?

oh it smokes! When I cut it down to stock I still hit 30#'s. I know this sounds like boost leak but I have been over all the boost tubes and connections 100X for leaks. I'm going to play more this morning to see if it will go any higher. I'm pretty sure my waste gate is set around 40+ #'s. It won't even fully clean up the lil smoke in stock at wot. My intake stays spotless so it can suck all it wants to when it needs it. Just tired of low numbers. Any other suggestions of things to check?

The Super B is a 57mm turbo.

Have you checked the cracking pressure of the wastegate? Try putting some regulated air on it and see what it opens at.

Many of the aftermarket turbos come with an adjustable boost elbow as well. I am not sure about the Super B, I'll have to pull one off the shelf.

I can't remember if I checked this one or my last one. I'll check it soon though. And the boost elbow is separate. But I double checked the clamp and it is tight and seated all the way. I was going to play on the way home but as soon ASI started the truck my CEL came on. Most likely under boost code like normal, but my pos bullydog would not read the code to clear it. I have determined that everything I get I messed up
