So I've bee having what I thought was a lack of power issue but when we ran test with the A E we could not find any problems with my truck except when I had my TS chip installed. It's all in another link. Since then I've done lots of work to the truck and no improvements. So I purchased a DP runner. The truck runs better but not as good as some others so Rick and I got together today and did some data logging and on stock my ipr duty cycle was around 35% and oil pressure was around 2800 psi. This was a run from 0-80. Same run on 120 race and duty cycle was at 98% and oil pressure was at about 1800. This doesn't seem right! It almost felt like it was running out of fuel. Is my hpop bad? Or can it just not handle what the chip is asking? I installed a new ipr and icp. Could it be bad o rings? Eventually I'll get er fixed up just like I want her. Thanks in advance!!

Sounds like a weak HPOP to me.

Go mod'ed stock if Joey is still doing them. My pressure was dropping below 2000 (maybe even 1800, IIRC) but Duty Cycle was only about 65% max with stock injectors. With the hybrids it only goes down to about 2800, DC is around 45%. I still dyno'ed 310/681 with those HPOP numbers. If you're never going with singles or hybrids in the future, investing in the HPOP is a good idea -- it is a little on the weak side.

Modded seems good but I thought that's all they did. Seems mine needs to be rebuilt. I was under the impression modding only improves what you have. For instance if it improves it by 200# would that make a 3000 psi pump 3200 and a 1800 psi pump 2000? I'm a little confused that's all. Help me!
