Lack of power?

Ok all I’m at my wits end with this one. I need some input.

2001 ram 3500 5.9 auto 4x4 drw hy35 turbo
3.54 gears trucks weighs about 12,350 without a trailer
Built the trans as well thinking it was losing power there.

When I bought it it was dog sh*t slow wouldn’t boost above 17 lbs. even played with tunes in the smarty jr.

Installed dpp 100hp injectors
No change. Just Smokey now.

Wired wastegate shut. Gets to 18lbs a lot faster.

Bought a used hx35. Wastegate wouldn’t fit it was off a medium duty application. So I removed it and wired it shut. Boosts 27lbs now.

I feel like it should be boosting a lot more than that. Also it’s hazy at idle and under light load.

Is it possible the pump timing is locked or something? What should I be checking for?

I should also mention the egt don’t really go above 1200 under wot but when I am rollin down the freeway and make it down shift it’ll start clouding even under full boost. 🤷‍♂️ any input is appreciated.

That truck naturally is going to be slow. You’ve also got minimal tuning at best, Smarty is limited on what it can do with what you have. Also, Smarty Jr for a 24v? I don’t recall such a thing but that’s neither here nor there.

A stock auto truck I don’t think hits 30psi, even with minimal tuning. The few I’ve been around haven’t.

If your pump were having issues like locked timing, you better believe it would be tossing codes.

I actually think your truck is about where it should be.
