180/100 smoke issue, tuning or need more air

[Dscrant]

I have another question that I can't find much info on. Recently fixed a crazy short causing fried IDM's (2 to be exact). Now that I finally got to drive her, I'm getting quiet a bit of smoke on my FFD 180/100 single shots.

Is this something I have to live with for full potential from these. I have 6 custom tunes ECO, TOW, DAILY, HOT, EXTREME, and DRAG. Even on ECO 1/2 to 3/4 throttle she's noticeably smokey (not just hazy)

Current upgrades GTP38R, 4" Turbo back, 6637, HPO X-over, Regulated return set to 65ish

On any tune past 3/4 throttle, it's a blackout behind me

I'm not an expert by any means but I would say you either need some different tunes or need a bigger turbo or even check for boost leaks

Ok, just finished checking. No boost leaks that I could see. All clamps are tight and boots intake, plenums look good too.

I figured that turbo would be sufficient for those injectors.

Tunes are still being adjusted. In constant contact with the tuner.
Is it possible I need to adjust the wastegate? I got the full package from Full Force Diesel, stage 2

Yes the Wastegate could be preset too low. Quick test will be to pop off the red line and go drive. See if it's better. You have the stock one? Prob need to tighten it up a few turns.

Boost gauge? What are you producing

I agree I forget about the wastegate because I've always had non waste gated 7.3's but yes the waste gate could be set to low. I would check that as well because that's free and easy lol

A visual check for boost leaks is virtually useless. You’re going to need to pressure check the system (10-20 psi) and listen/soap check for leaks.

Yup, I'll use some snoop leak check after work. I'm getting a temp gauge setup because I haven't decided a direction for permanent gauges yet. I'll post an update after work

Pressure test charge air system first. If all good just unhook the red line for wastegate and see if that clears up the smoke. If it does then wastegate needs adjusting.

How much boost are you seeing wot right now? What's your egts wot??

honestly you are always going to have smoke and egt issues with those injectors, we really try to not even push those anymore. I ran them for 3 years with drop ins and full t4 setups and never could overcome it. Getting a improved turbo will help some, but ideally changing injectors is going to be the best option. Going with a kc300x 63/73 turbo would beneficial as well to a degree, but the problem is the 100% nozzle in my opinion.

Thanks jbolen323... unfortunately all of this is brand new and I didn't research enough before purchasing. I may have to just suck it up and deal with it until I can get different injectors. I appreciate the input.
