And it didn't put down anything near what I expected it would 
.
Best pull was 382/545. The tune I'm running I'm told has/should dyno around 450 HP. I'm just a wee bit short of that. I dynoed 440/820 a whole bunch of years ago at one of Merchants big get togethers, and that was while running a dirty predator tune and losing some serious rail pressure.
Something doesn't seem right, but while I don't quite understand some of what the log shows, for the most part (unless I'm missing something), all targets were hit. My first and third pulls were with the 450HP tune, the second was with another, older tune that *in theory* should put down more, but I lost major rail pressure on that one, so that could explain why it didn't make much more power.
One of the things I don't understand is at the beginning of the pulls, rail pressure dropped off by about 2k from desired, built up to desired, but by the end of the pull, desired was just about 4k less than it was at the beginning. There's something similar with the boost - about half way through, the desired boost dropped off.
I would initially think it's something mechanical, however, if that was the case, wouldn't I see something not hitting it's target, like losing big rail pressure or boost?
Does anyone have any thoughts?
