[@andrewkuperstein3892]

Thank you for everything you do.

[@greatmusic9494]

I really appreciate these 12 valve videos you're doing! Expect an order for injectors and gov springs from me soon. RCarlson

1 flat of a bolt is 1/6 of a turn. A bolt head has 6 sides. But again, great info guys ive got my 12v dialed in pretty good after watching your videos and using your injection parts. Thanks for the great products and videos to back em up

[@The.psmith]

[@joelmitchell8448]

[@timlarson9193]

😂😂😂 not gonna lie! I laughed when I saw that flatbed out there haunting you!

[@themanchannel8761]

Great info! And I love North ID. Hope to make back there some day.

[@bcbloc02]

I can't wait to try my new 4's to see how they drive.

[@t3dieselperformancerepair228]

Very good info!!!

Good vid like always Lenny and Mitch. Perfect timing uploading this while im getting ready to put a p pump engine in my 1st gen and want to start up easy. My truck is a manual so higher idle rpm would be great.

[@user-hp7my3tq3b]

Lenny and Mitch back at the 12V stuff again...freaking awesome. Now Lenny, two questions, since I already have my hot pump, delivery valves injectors, turbo, can I get a backstrap off of ya. The truck took a little away from hunting season. Next, I like the ol school groundhogs or irocs, whoever makes them anymore, looks good. Appreciate this DDP

The cummins wizards!🧠

I've gotten pretty good with my toe to make it start instantly like a VE pump but not puff a cloud of smoke. One thing I would like to improve is maintaining RPM when letting the clutch out in 2nd gear with no throttle. I realize it'll never be like an electronic engine, but better would be nice.

Where do u bind Bosh book?

[@freddyleos]

Curious to know what the towability is like?

[@tuffy16]

I picked up a 1998 auto P7100 P pump cheap but the one stud that holds the governor springs is broken any idea where to get parts?

[@freddyleos]

Hey Lenny, you should sell me this truck when your done with it!!!

I have a 1997 2500 HD, 8,800 GVW 215 HP with a 5 speed manual. It has almost 359,000 miles on it. You say that you sell an afc foot. What do you think about PDD'S afc live? They take the foot out, but you say that it is better to have a foot in the afc. This truck is completely stock at this time. I have to change out the gear housing because the dowel pin came out and broke parts of the case, and I used epoxy to seal up the areas that I could get to. I have bought 60lb springs, 3,000/4,000 lb. governor springs, PPD'S afc kit, 4" exhaust, HD head bolts, 055 delivery valves, K27 turbo, EGT and Boost guages, 13" flywheel clutch package good to 400 HP. area. I would like to end up with around the 350 HP. to 400 HP. at the tire. I have not bought injectors yet because I do not know if or what to buy. What would you recommend?

[@JohnEvans-oq5sf]

You need to call them. They almost never answer on KZbin.

[@bcbloc02]

afc live still uses a foot but it is a different foot.

32:15 Where the heck he found 12,5mm plungers?

[@bcbloc02]

They had them custom made.
