[QUOTE="maplemale, post: 1134644, member: 17366"] Update: Well... I've pretty much been ignoring this. Though at about 35 - 40 degrees the smoke is about 5 times worse than my video. But, now two days ago at about 30 degrees (had been down in the 10s that night), she won't start. Tried to start her 4 times. No go. Lots of white smoke the last time and one romp then dies. I gave up for fear I was going to hurt something. :wtf: The oil has less than 1k miles on it (DELO 400 15w40). The fuel filter has about 5k miles. New GPCM. New GPs. I'm insanely busy right now and didn't have time to omh out the GPs at the harness. So, I bit the bullet and am paying a local shop to do it. Still waiting to hear back, should know tomorrow. Maybe it's VCHs? No idea... Two more thoughts and possible clues or possibly nothing: 1: I do get what seems like wet stacking when in town. That just part of having slightly bigger injectors or maybe point to tuning issues? Basically, when I'm just driving around easy up to about 40 mph with no hard take offs (RPMs always below 2k) I notice no smoke or anything. But, the first time I take off like a bat out of h3ll, it will fill a 4 lane road with grey smoke for the first 200 feet. Then, clears up and wont' do it again unless i'm idling a lot in between take-offs. It's very much like I'm building up excess fuel from idling and then burning it all up at about 2800 RPMs. 2: Check out my emissions results from before Stage 1s and after Stage 1s. Should they be this much worse? [url]http://www.thedieselstop.com/forums/f24/emissions-testing-denver-482650/[/url] Going from 5% at 40MPH to 21%? All of this was in Matt's economy tune. Is that expected with stage 1s and this type of tuning, or maybe this is point to possible clues? Maybe all this is tuning. Seems like a huge opacity increase for just stage 1s. [/QUOTE]
