Lb7 need help with upper valve cover
Mine did that on the driver side... It was stripped from the previous owner's injector job. Ended up taking a zip grinder and grinding the head off... Sent from my iPhone using Tapatalk -
LB7 Voltage Dip
The more I think about it; the more I see some weak battery symptoms... (Could be all in my head of course). Lights dim when I put the windows up. Cold starts during the warmup process, voltage is below the 1/4 mark (above 9, below the mark below 14). I'll have the batteries tested, just to... -

Not aftermarket, no. OEM replacement from O'reillys. I'll check the output cable also. -
LB7 Voltage Dip
Interesting - never thought of that. I'll have to try it this weekend and see what I come up with. It should also be noted that my heated seats no longer work; I think the elements are burned but these issues could be interconnected I suppose. I first started to really notice the voltage... -

03. Battery light never comes on. When my alternator went bad in November, I would get the light and the DIC read 'Battery Not Charging'. Obviously when I swapped alternators, that went away. -

LB7 Voltage Dip
Hey everyone, Strange issue that I've been battling for a while.. I'll be going down the road, and when I let off the gas, occasionally all my lights dim for 1-2 seconds and the volt meter drops to 11-12 (don't have an exact, just judging by the gauge) and it kicks off things like my heated... -

LB7 Tuning Questions
So, I've got a couple questions about tuning my LB7. I'm gonna buy the Mild Max Autocal from ATP, as soon as they re-open on Friday. Anyway, my questions are: Does anyone run a "winter" tune? I'm curious as to if a tune optimized for the cold weather is used/has been developed. 2) I've ordered...- OnixMax

LB7: Need help with some decisions
Obviously you know you need injectors. Find Brent@LDS on here. Lincoln Diesel Specialties has the cheapest and great quality injectors. I did mine in January and Brent helped me over the phone and email when I hit a road block. I'd go EFI Live tuning. Idaho Rob seems to be big on this forum... -
Help 01 LB7 Wont go past 2000rpm
It took a while to throw a code. I have a scanner and when I scanned it, the code showed as 'pending' but didn't light up the CEL. I forget what code it was; I think it was pointing to the FPR but was really the FRPR. And yep, just used a multimeter and stuck the end in each pin on the... -
Help 01 LB7 Wont go past 2000rpm
Check the voltage in the fpr and frpr sensors. Same happened to me, and one of the wires in the frpr (right side of engine by the fuel rail) was pulled out. Replaced the pigtail and it ran phenomenally Sent from my iPhone using Tapatalk -

Exhaust question
I REALLY don't want it to be overly loud. To me, the stock exhaust sounds pretty good but I want the better flow and lower EGTs. What scares me is I pull trailers with regularity with my Dad, and I don't really want it to be loud. I actually don't mind the sound of a 4" Flo-Pro (YouTube), but...- OnixMax

Exhaust question
I've read good and bad about the "quiet tone" front pipe from DE. I mean, worst case, I pick up a 4" MBRP exhaust w/ muffler, and If I don't like it, I could just replace the muffler with a longer one. I've read too that MBRP produces a "quiet" muffler.. Sent from my iPhone using Tapatalk- OnixMax
