Excessive Black Smoke

[jmcgillkx99]

I just installed my dp-tuner chip with the 40hp tow, 80hp economy, and 120hp settings and it smokes like crazy even at half throttle or less. I have a 96 OBS with 3" downpipe, 4" straight pipe, afe 4" filter, 6.0l intercooler, Beans stage 1 160cc injectors and the chip. Before I installed the chip the pickup wouldn't smoke at all even with the injectors and now it seems a little excessive to me (half throttle can make the car behind me dissapear even on 40 tow). I was doing some research and saw that clogged intakes and leaky intercooler pipes could cause excessive smoke. So I cleaned my intake, checked out my turbo and smoke tested my intake system and found nothing wrong. I was wondering if anyone had any other ideas? Should I have my intake system pressure tested? Thanks, Jon

Ever since I did the intercooler I have had bad turbo lag but its much better with the chip but at 2200rpm im a bout 10psi up to 27psi at around 3000rpm

10 seems low for 2200 rpm
Yea I'd pressure test it to see if there is a leak. What kinda EGTs do you see

The little bit I have been able to open it up I have not hit more than 1100 degrees

Where is the EGT probe at? DP or manifold?

well u wouldnt have gotten any smoke or power out of stage ones without a chip, since the chip is what makes stage ones give power and smoke, ur turbo might be bad

Talked to a local diesel shop and they agreed with me that I was getting to much fuel on top end talked to DP today and they are going to fix it for me.
