    LB7: lbz regulator mod and drivers manifold are they worth it?

    Yes I agree. i have a lly cp3 on my lb7 but a new lb7 fpr. my tune is calling for 27000psi and im only able to muster a lousy 21000psi at a 100% throttle. But when I let off pedal it spikes to 26000psi momentarily I think ill try the lbz reg.

    LB7: lbz regulator mod and drivers manifold are they worth it?

    Anyone have any concrete evidence that a lbz reg swap will definitely add fuel rail pressure. :confused:

    LB7: lbz regulator mod and drivers manifold are they worth it?

    Allison 5sp: manual shifting or leave alone

    Well I noticed a little better spool up when I first did it but I had no mods at all on truck. So it worked then. The heater is located below your map sensor on intake housing. I bought a cummings diesel drain plug and plugged the hole where the heater was. I did not use efilive to delete it...

    Allison 5sp: manual shifting or leave alone

    I have been a drag/street car guy until now. I like my 10 sec cars but just too much of a hassle to keep them streetable and enjoyable so I built up the dmax My question is. Is it common to manually pull truck to a lower gear when wanting to stomp the pedal like I would in a street car or...

    LB7: lb7 slow spool up problems

    Ok now is it my cp3 that's a little week or is it the regulator. Ill install a lbs reg and tune for it if that helps. Like I mentioned before it seams fine on dsp level 4. But I also notice that it does not do it on 70° low humidity nights. Im probably just being picky on hot days. I...

    LB7: lb7 slow spool up problems

    Today I checked all connections and all is well. I hooked it up on efilive and logged it I am going to send it to Idaho rob to see if it needs fine tuning. It only seams a bit slow on spool up during my high tune. Down on 4 of my dsp 5 switch it spools faster but don't run as strong as level 5...

    LB7: lb7 slow spool up problems

    I bought a used pump from tony at allseason diesel and I removed the original reg and installed a brand new lb7 reg. I don't think it matters but the cp3 is from a lly but i definitely put a new lb7 reg.

    LB7: lb7 slow spool up problems

    I am having a problem more often than not. If I am cruising 1700 or less rpm and lay into the pedal my truck seams to just pause for like 3 sec. it puts out a extremely amount of smoke until the turbo gets spooled then it pulls hard. im fairly new to turbo's and diesels but in a gas drag car I...

    LB7: lack of power after cp3 install

    Yes I agree but I don't own a efilive unit. A friend has one 20 miles away.but I will get it logged asap. I just think if I was to install a lbz reg on my truck would run better than it does. Thank you

    LB7: lack of power after cp3 install

    I am sure the problem was cp3 or regulator. I had a loud buzzing coming from reg. The truck ran great but there was a time or two recently (before cp3 change)that the truck felt like it ran out of fuel in 4th gear. Now I dont have the buzzing of the reg. But I feel I lost top end pull slightly...

    LB7: no starting /cp3 pump or fpr?

    Well went to allseason diesel today. Bought a cp3 and new fpr and installed it with some new much needed rubber fuel line but would not start still. New cp3 definitely felt better than old one at 250000 miles. When I installed the cp 3 I blew through all lines And they were all clear. My air dog...

    LB7: no starting /cp3 pump or fpr?

    I removed my factory filter and have rubber lines where it was. Today when truck stopped running the first thing I did was pull lines and I had tons of pressure there with pump on so I went to the return line and have nothing. Real confused here. I removed cp3 today not sure what im looking for...

    LB7: no starting /cp3 pump or fpr?

    Unplugged for and still nothing. Took off fuel line return and cranked over with and without lift pump and have zero fuel coming out of return. So either something is plugged or cp3 went by by

    02 lb7 I installed robs efilive on fri. Today it started and ran for 10 sec then stalled now no start. I have removed my factory filter and installed a airdog 165 a month back or so. My filters have 1500 miles or so. Now I have a humming noise coming from fpr. I don't own a efilive but had...

    all hell broke loose Mike Thank you for your assistance. I know you do not need to help on a trans you didn't build. I thank you for the help. Last night I had a p0741 show up with my temp climbing. So I reset code and went for drive after resetting tune to stock. Temp continued to climb to...
