Boost problems
 

I drive a 1998.5 24v cummins, my boost gauge says I'm only putting out three to four psi of boost, is there any certain places to check for leaks? I don't think its the wastegate but let me know if I'm wrong!

Check all your I/C boots. The lower ones can rub through on the inner fender and cut them. You should be able to hear a leak with high boost pressures. Add your signature so we know more about the truck and can help you easier.
