In this build series, we restore our tired old 2002 GMC Sierra 2500HD, 6.6L LB7 Duramax Diesel. We replace 90% of the body and add tons of awesome aftermarket parts. When we're finished, you won't be able to recognize this truck! In this episode, we get the truck tuned by Precision Diesel using EFI Live V2 and add a DSP5 Switch. We also undercoat the truck using Fluid Film Black.
Here are the 5 tunes we can select from:
25Hp Lope tune
45Hp Economy tune
75Hp Towing tune
120Hp Street tune
150Hp Racing Tune
Here is a link to the undercoating gun we used in this video:

I just did some work on my friend's mothers 2003 Chevy Silverado; she wanted a rust protector, so I sprayed the truck with Woolwax. I have put it on three of my trucks. If you build it up thick on the first spray it works really well. If you do a second or third touch up it will last longer. I check once a year and do touch ups as needed.

Yeah our undercoating didn’t hold up to well through the Canadian winter 👎 we’ll add some coats this spring though

Right on! Hopefully you learned a thing or two. The next episode should be ready soon.

Hey brother you really need to buy and install a Lift pump. As these trucks get older with more miles the CP3's internal low pressure pumping gear set gets worn down thus not flowing as much fuel as it should. Also the feed lines can get sucked shut/collapse on bigger tunes because the stock setup sucks fuel from the CP3 in the engine valley all the way back to the tank through some very soft fuel lines... Installing a lift pump will keep them open from pressure vs closing from suction, not to mention it's much better fuel filtration which saves injectors... Your truck looks to me like it's probably dropping rail pressure because tune 3 seemed just as fast as 4 or 5 with the same smoke output. They should be noticeably different.

Hey man, thanks for the great advice! Yeah we’ve been meaning to get a lift pump, but haven’t had the chance to do so yet. You’re right about tunes 3 to 5 being similar. Our injectors were replaced once, but that was a few years ago and a couple of them are borderline within spec, so that’s not helping the situation.

Where'd you get the lope tune for the LB7?

@Phabian_Phabrication 4 ай бұрын

I’m interested on this whole list! Can i do the same to my truck being out of state or does it need to be flash tuned in house?

@Motorbolt 4 ай бұрын

The guys at Precision Diesel did all the work, so you’ll have to reach out to them for details about the tune itself!

@Motorbolt 4 ай бұрын

I think they have to do it in house, but I’m not 100% sure.

Any update on the under coating? I got surface rust I’ve been wanting to clean up and been looking for something for a while

@Motorbolt 6 ай бұрын

Honestly not a huge fan 👎 It held up fine for the summer, but the snow and salt from the wheels flaked off most of the coating. We’ll keep adding coats every few months and maybe eventually it’ll build a stronger coat, but as of now there’s barely anything left.
