Turbo Boost? Need a turbo overhaul?

[EArmsF350]

I'm watching my ISSPRO turbo boost gauge and never see it exceed 16psi, even when pulling a 24 foot stock trailer. Called performance shop and they said I should see pressure as high as 21psi. Is this where it's supposed to be. 70 mph highway travel shows no more then 3psi. The truck does seem to be sluggish compared to my dads 7.3 PSD. Both are 2000, 4R100, 211K + miles on each. Dads is a 250 4x4, mine is a 350 dual 4x4. Shop told me to check the clamps on the intake in the valley, said there might be loose clamps or my turbo needs overhauled. Said it would cost me $1400.00 to rebuild the turbo. I don't know if he included the price of the Wicked Wheel or not. Is this price he norm if a shop does it? Is the Wicked Wheel the way to go if the turbo needs re-done or not. Disclaimer states it does nothing for the performance of your truck it just stops flutter. New to turbo problems, please send advice and knowledge. Thank You in advance, Eric.

Definitely check for boost leaks in the pipes. also check your up pipes(behind turbo) that could cause a leak. and 16 isnt bad for a stock truck but you should be able to get a lil more if you unplug the wastegate line(red one) but thats average for stock.
wicked wheel is a great upgrade. spools up good now i think.
check your turbo shaft for play, if it has alot then its definitely shot.

We looked at the up pipes this afternoon, they looked good. What does the wastegate do? And explain why it would give me more boost if you dont mind, I'm learning.

if releases boost earlier. so unplugging it might give you a lil more boost. its that lil red hose on the right side(if you're lookin at the engine compartment)

So it wont hurt to unplug it and leave it unpluged? Does it have something to do with redirecting exhaust heat to help the motor warm up in the cold season or is that something else?

if your truck is stock and your hitting 16 psi at WOT you have nothing to worry about i would say.

[EArmsF350]

Well if 16 psi is good for a stock truck why the @#%& am I lagging so much power. I cant figure it out. I've replaced and cleaned everything other than the electrical componants. What do you guys suggest to look at next. I'm just experiencing a sluggish 7.3.

16 psi is not bad for stock, I run mine stock the other day and pushed it to right at 18. I would just check all intercooler clamps, you may have a very small leak. Honestly my truck is a slug without some kind of programming.

ebpv....closes to warm it up. the wastegate just releases excess boost.
