I had a local Ford mechanic that works at the dealership on 7.3L and 6.0L only tell me that stock boost for a 7.3L is 13-15psi and even chipped, intake and exhaust he has never seen above about 21psi. Does that sounds right? I was under the impression that stock was around 18-21psi and modded could be up to 25-27psi. What numbers on the 38R and Van turbo? Just a thought, thanks guys.

 

That guy was lying out his *** too you..... I only have very minimal stuff on my truck and I can hit 24-25. The big boys are hitting over 30.

 

Thats more what I thought I had read over and over on here, but I thought maybe I was wrong. I will have Brandon set him straight when he comes out next week Thanks for the help Cris

 

Stock is more like 17psi.

Chipped, intake and exhaust I can easily hit 28 psi....maybe more, I don't really look at it (and it's been over 5 months since I've driven my 01 )

 

Where you been boss? Are you not a sponsor anymore? I haven't seen you around helping all use suspension newbies

 

Been around, still posting....although more so in the SD forum lately it seems.

And you'd be correct, just a regular member now.

 

That mechanic is freaken crazy i can hit between 31 and 33 with the wastegate unplugged and about 29 with the wastegate plugged in

 

if i really stand in mine it has a bigger turbo,a ts chip and 6637 mod and i can burry the guage on 40psi

 

There is no way on stock sticks plain TS chip and a Garrett turbo need to check your boost gauge.
I see 25 on mine but I haven't really payed attention when I am WOT.

 

They guy is nuts, with the exception if you don't have a boost fooler device ?
In stock form if the MAP sees anything more than 17psi, it drops boost and sets overboost SES.
With a regulator or something, you will get more. I get over 20# with no issue. Towing up a grade, I can easily get over 30#

I was getting 30+, stock turbo and sticks. With DP-TUNER of course. Now with the TN BB and SS Stage II's, the last time I looked I was at 33#, I think I can do 35#. I watch the egt gauge more.

 

unless my guage is wrong or something it will go all the way to 40. i do now know what all has been done to the motor all i know is it has a garrett ball bearing turbo boost anhilator and a ts chip.

 

What kind of boost do you show going down the highway?

 

I've only got a wicked wheel in my stock turbo, with the water meth it'll hit 32-33# but I wont let it go higher with the meth b/c I havent done headstuds yet and I dont want to take a chance. And I leave the WG line on for the same reason

 

The most Ive hit is 28 on mine
