Fixed my stutter but new questions.

Ok I just bought a new crew cab Z71 so the DSM got to go. I had the MBC set at 15-16 psi on my 14b and it bogged and stuttered. I was too lazy to really do to much work to it after I got my truck. Now that the car has to sell I finally got around to doing some work. For some reason my MBC wouldn't go any less than 15 psi. I suspected that the boost was too high and knocking like a motha so I put the stock BCS back on and took the MBC off. It is now boosting 9 psi and running smooth to redline. The car just has no power. I might be since I used to 16 psi. Is the 14b at 9 psi slower than the T25 at 9 psi because of the effiecency ranges? Should I put the T25 back on? How can I up the boost alittle to get some more power without going to 15 pounds? If I missed anything let me know.

Check it for boost leaks

There is a tiny tiny tiny one by TB I couldn't find. I know there should be none but this car is about to be sold. I just want to raise the boost to around 12 or 13 instead of this pathetic 9 right now. Should the MBC be able to drop below 15?

Should the MBC be able to drop below 15?

Yes.

if im not mistaken the 2g's come stock with 14.7 psi so you should be fine with 15 psi.

You are mistaken 2g's come around 9-10 psi stock. Most people can run 15 with no problem but I was knocking horribly so put the stock BCS back on. I'll try the MBC again.
