So after getting more drive time on the new tune the surging is coming back. Seems every time I reflash a tune the surging is alot less at first and slowly gets worse. Not only that, after doing some data logging on a few WOT passes rail pressure is dropping to 18k psi.
According to my couple of passes at the strip over the weekend my trap speeds are putting me at about 650 hp. Something is definitely wrong and I need to figure it out. :doh:
And I was never worried about rods. LOL Don't think I'll ever be.
what are fuel temps when the surging starts?
160k on the factory pump. I know it probably should be replaced soon but I don't believe it's the root of the issue. And I'm unsure about the PCV and VCV.Is it possible that your pcv and vcv adaptive learning is playing a role in the surging? And how many miles are on your hpfp?
Josh hold Erics hand on tuning.... I LOLed there

I'll have an email sent out to you shortly with the info. I really appreciate it.Hey man, would you wanna email me your truck info and everything and I'll turn stuff to josh and see if one of our calibrations fixes it?

There is an adaptive learning function with the regulators on the pump... could be messing with your game.
What do I have to do to reset them?
What is your low pressure fuel set at? What psi? A k16 will hunt and surge if you go over 5-7 psi. Go over that with a cp3 and it compounded. I sent you the file that's in my truck tonight. Tune did 7.45 @94 mph in the 1/8 on mud tires at 7,800lb with stock appearing turbos.
Strange.... what size nozzles again? Any way to shut the cp3 off to see if the k16 even works?
So I loaded up Josh's race file. Did a few WOT passes and I'm getting low rail pressure. It's about 15k psi with PW at 2.3ms. Could my K16 be that bad where it can't keep up even with dual pumps? Curious if it is the root cause of the surging as well.
