Dynoed the truck.....

- Start date
Mine feels ok, runs great. Just isn't as cocky as it was with my IHI, I used to lean on it at 30-40 and break the tires loose, now it seems to be a bit laggy and doesn't have that same "punch" 
Is it just because the power is more progressive and smoother transition from slow to holy **** fast, the speedo sure moves quick.

Yep it's still limiting fuel, I am going to run it just for the sake of logging it I will post the logs, someone please tell me what's limiting me!!!!! I'm going to give up on this....
Here are a few logs from my truck, I see that the fuel is being limited..... I only see 88mm3 or around there, when it runs good I see up to 126.9 mm3??? What could cause this???
Things I've already changed hunting for a solution to this issue:
Engine harness
ECM
Tuning
Trans was re-done (had issues)
New lift pumps

All these issues started after I had a CP3 explode!! There was shiny filings in my fuel filters for about 3 months after it happened. I guess we will be looking through all the fuel plumbing on the motor to see if any fittings or valves are plugged up....

Also wondering if the used LBZ FPR I bought from a member here could be the culprit? I get no codes for it though....
Contacted the guy I bought the FPR from says it was fine on his truck, he upgraded to CP3 X2 and used II bag of parts, came with new FPR. JRODSLB7 was nice enough to let me try his MAF and intake since we have the same one :hug: truck felt good as per usual when we change something or re-flash... but on my way to work this morning I could tell its starting to get lazy again, I'm willing to bet that on my way home later it turns into a complete turd again.......
Going to swap out my FICM next, I guess we will keep changing shit til I find the culprit!! I also have a throttle pedal laying around, I might try that after the FICM if I need to......
Anyone have any suggestions what to change, where to look??? Any input will be greatly appreciated.

Justin i have a few sets of lb7 fuel plumbing you want me to send you some stuff? i can look and see if i have a spare fpr,i dont think i do but if i can find 1 im willing to send it for testing.your truck should be in the low 12s for sure.
Yes sir, I can get an LB7 FPR from James (JRODSLB7) we decided to start changing parts one at a time until we get it, hope we can get it before its too cold, I need to plow snow with it as well
Thanks!!!!!:thumb:
