UPDATE, No more smoke other than a light puff of black after some carbon build up lets go on a hard throttle.
I can tell that there is no more skip'n or surge while on the throttle. So far(fingers crossed) this Mr gasket diesel pump is holding up....been on about 700 miles now.
As far as the CAT...well dont "you all" know....we'er a bunch of slack jaw'd rednecks here. We have an obdII scan and a visual. But as you all know they dont throw codes without a CAT and they never look under a car here. Now, if your a Yank its a different story

JK! But really. They arnt that strick here.
