Which ones have u tried and if 14 was ur favorite why was it I'm running the latest update whichever that one is and I think it's got to much timing it's just to clean for a diesel not even a haze at wot.

I've tried ME 14,17,18,18 TNT, 23,23tnt and I believe 25
Who did you get your smarty from?

The more timing you have, the more fuel is introduced early thus creating smoke. If I remember right the smarty doesn't shoot a ton of smoke with the 6.7 like it does to the 5.9

I bought it from a guy here in my hometown he blew 3 hg with it running on the 90hp setting but he was pulling a big cattle trailer when I first got it it wouldn't load to my truck is was a 2010 so he updated it for me now it works I'm not certain what version it is I just assumed the latest, as for smoke I'm not really out for clouds just like to see a good haste at wot that's just what I've always been taught a diesel should do as far as fueling goes.

True but smarty has gotten clean they have come along way are you running a Jr or the s67

S67 I'm prolly running a little on the safe side as far as rail pressure and the timing advance you can do on it scared of messing a factory injector up idk how much they can hold, oh and I have an aftermarket turbo it's a 62 phatshaft shoulda went 64 or 66 but got a good deal on it I hope there wasn't something I missed on the delete part of the factory turbo removal there is a small hole where a hard line screwed in by the thermostat housing I left it open maybe u know something about that I'm full of questions I know thanks for the help

If I remember right I ran my rail pressure at 2, turbo on 3, timing on 2-3 to much of that and you get bad rattle, and torque man. On 2-3 and I ran sw8 constantly. As far as the turbo I'm not sure man. I can research it though have you checked out cummins forum or maybe call industrial injection and see what they say about the turbo

No haven't talked to anyone bout turbo but it hits 45 lbs already real easy, did u have headstuds on yours while running this and my egt gauge is messed up I got a new one on the way what was ur gets like.

I didn't run gauges man no head studs either but everything seemed fine I'm on efi live now pushing it even further

I thought about trying me14 but have had a lot of people tell me that was the head gasket killer and I'm for sure not wanting to mess with all that headache yet

14 is a really aggressive tune it runs good but smokes like you have a 100 tires burning in the back of your truck. I blew my hg with this tune so have many others I would stick with what you got. I wouldn't be running much high timing either. I believe running high timing helps push the hg out also but I could be wrong there
