completely blacking out the right lane right in front of a duramax priceless
The PE COMP is a timing box AND Fueling box for about $700, at rallies and events the prices can drop purty low

. I paid $575 for mine.
Heck just talking around to TDR members can get you good deals too

I bought some brand new DD1 injectors for $350, and they came with a free fuel filter.
All ya need after those two upgrades is a clutch.
I recomend a South Bend Clutch MU 0090 Con OFE (not for the light of wallet) (~$800 + installation)
If I would do the smoke show over again,, I would go straight past DD1's and go to some Supermentals,, or for a little more smoke I've heard the BD5's are better at Mosquito control.
A BIG turbo will increase the smoke, because it will increase the time before your turbo spools up,,, if your turbo isn't spooled up,, that's when the image of "smoking like a freight train" comes to mind.
A BIG turbo will also decrease smoke and EGT when at WOT by giving your motor cooler air, and less backpressure on your motor.
I have noticed with my truck,, PE COM 5/5 and DD1's if I take off a little quick My pyro instantly shoots up to 1000* and then when the turbo starts spooling up a little bit the EGT starts falling, but at the begining of each gear(after a shift), before the turbo starts to spool up, my pyrometer swings up purty darn high.
If I am in 5th gear @~1300RPM and go WOT the pyro will climb to 1200* before my stock HX-35 starts to spool up. My truck also accelerates slowly when it's puffing black smoke, when the turbo spools up, and the black smoke starts to clear,, there is a nice "push" in your back until about 95MPH when the engines starts hitting redline and the ECM cutsback fuel.
I hit 1400-1500* under WOT in 5th gear, I keep temps that are over 1300* limited to less than a minute, and anything in excess of 1400* less than 15-20 seconds.
That was my rant about smoke.

PS I got off subject,, I guess I would have been better of in the TDR chat room.
