So I put a good working turbo on my 1996 GMC Suburban and there is a big improvement in performance, obviously. I also did the turbo master trick and on big long hills I can get up to 10PSI boost. But now I have to address some other issues. When taking off I initially get good strong...

WooHoo! got it working! Thanks so very much for Paveltolz letting me borrow the spare he had laying around. That did the trick. Here is a couple of lessons learned. Don't wire your wastegate shut for trouble shooting, that doesn't work. There is a tremendous amount of exhaust gas pressure...

yup, MAP replacement didn't do anything.

Thanks Guys so much. I've talked to a few diesel techs this morning and basically got all the same advise. One thing however... I'm about to throw on a new MAP sensor for the heck of it and see if I get lucky... it's a stretch... Paveltolz, I may take you up on borrowing that turbo for...

Yep, wiring it closed.

Also, what brand of crossover would you recommend? I'm not going racing or anything, I just need a good reliable vehicle to tow a camper through the mountains to take the family camping and dirt biking.

Checked and double checked. Thank you. FYI if you have a stock crossover find something smaller than a golf ball to check for obstructions! I got a golfball stuck for a bit... THANKS JiFaire for that one! On that note,this is a good way to illustrate how restrictive the stock crossover pipe...

Thanks so much for the suggestions! I don't think the turbo has ever worked right since I've owned it. The only time the Suburban really has any noticeable power is in the winter and that is the only time in the past that I have ever heard the turbo whistle and the whistle was only on occasion...

Help! I have no boost pressure and I can't figure out why the heck why. Here is what I have done so far to diagnose. Removed the vaccum pump and did the turbo master trick. This really didn't do anything to make note of... Second, I bypassed the muffler and soot can and ran open pipe...
