Deleted my buddies 15.5 lml this weekend. First one I've played with. Had all of 12k on it but had the emissions crap put him on the side of the road 4 times. He sold his 01 8.1 gasser wanting he diesel and better fuel mileage when towing along with the reliability.... needless to say he was pissed the last time an egt sensor went out, threw him in limp and stuck him to 30 mph the rest of the way to page where a ford dealer had to fix it (no Chevy dealers there). Called me and said "f**k this thing, send me a list of what I need to order and let's get rid of some of this bull shit". Say no more. Full flo-pro exhaust, mbrp down pipe, deviant egr delete and new up pipe, lift pump, trans pressure mod, new internal/external trans filter, new fuel filter, transyn fluid flush, s&b intake, cts2 w/egt probe and tunes by omnipoint diesel (mr chaves91). Cp3 conversion will come at a later point.
Thing runs good but I guess I was expecting more. Threw a max effort tune in for a few runs to see how rail stacked up and just holding 4th gear (trans had not learned yet and was not about to do wot through the shifts) it just didn't pick up and go like I expected. Think I'm too use to my rig. Dropped him to a 1300uS tune and he's very happy so that's all that matters.
I actually expected working on it to be more of a bitch than it was. That was a pleasent surprise. Much more room under there than I though. Specially with the egr gone
