186 2789 49.22
The runs are 45-90mph....even though these numbers look good,and the truck is still climbing speed,the oil pressure is droping..I know DP detunes the truck when cold,though not sure where it changes....I will say these numbers are better than the first two which,the 1st at RRE was 2200psi in 120race,the second appx 3 weeks later and it was 2400psi..the difference is at RRE the runs were appx 3-5 miles wot runs on the interstate, the others are 45-90mph runs and off the pipe..I read somewhere to test the HPOP is wot for 10 minutes in park..Na, i dont like that idea....

Joey, to answer your question, no, 85e is my strongest tune....
Thanks for your help...

oh and at idle ICP 480 IPR 9.77

IIRC, I think it's at 160*

ok,so is it in the tuning????spoke with Jody at RRE and he says not enough oil,that is why the testing started.....

also will that explain why the oil pressure drops????

Bulla, are you holding that pressure????Isnt that close to what i am seeing
oil temp 186f ICP 2789 IPR (dc) 49.22...these are max numbers and ICP starts droping from there.....oh and in the 120 race tune....

Yea thats about right. So why did you think it was only holding 2200? Was the truck completely warmed up that day?

yes---318hp 550tq, but i dont remember how warm the truck was....so that may have been before it got up to temp,i dont remember....hence, the testing..

,the 1st at RRE was 2200psi in 120race,the second appx 3 weeks later and it was 2400psi..the difference is at RRE the runs were appx 3-5 miles wot runs on the interstate, the others are 45-90mph runs and off the pipe
