Maybe this is why the 20K has a bad reputation... so many people running 16+ psi and it does not sound like that's where it should be at (aside from the guy with a standalone haha). Could have some blown engines soon? I'd be curious to see everyone's ECU numbers and have them open it up to check if there are some extra bits in there. I'm guessing Rob's tune will be more in line with the 550 tune, just better tuned for our gas at different rpm's.
Look forward to seeing what happens.
