Also you siad you were getting a knock sensor code, another thing you have to look at is if youi were getting KR or not. If the sensor wasnt working or you have it removed you have no way of knowing if you are getting KR, it doesnt have to be audible for it to be killing power.

You need to see if the knock sensor code resets. If you have washed you're engine you may have gotten water in around you're knock sensors p0327 or p0325? The code will set on the first drive cycle and affect performance, but the light may not come back on this the second or third drive cycle. My truck did this last week just felt a little lazy then the light came on.

Don't base your trucks performance on dyno numbers.
Get a second opinion, see if you can find another dyno and compare numbers.
What's more important, how much power did you gain over the previous mods/dyno?
Your a/f ratio looks fine and you mentioned 27degs of timing; save your money and skip on the dyno tune, not worth it
If you can get some logs, send them over and I'll take a look at them.
Also, something that is very important, how's the truck feel, how does it hold up against other trucks on the street, that'll tell you if it's running ok.
let me know,
allen

you can't just put some bolt on and get up to 400+WHP. Flywheel and actual wheel HP is different by about 20%.

well went back to the dyno today, all that was changed from the first pulls posted was bigger injectors and a walbro intank, she put down 378/381 and he stopped the run at 6200, the graph did not plateau so im upping my shift points which are 6200 now.
the dyno was on the heavy 20's, street trim, Now im off to install the 125 shot to hit over 500rwhp!
