You could always do trifecta. He ships you the cable to load the tune, for a fee, and then refunds you the fee for the cable or you will need to find someone with HP Tuners

Ah ok we're thinking outside the box enough now haha 
but why would it only start skipping once the motor warmed up to 151degrees? Because it goes into closed loop and the sensors start picking up the different intake?

I had the same thing happening to me. Replaced everything i could. Come to find out my injectors were getting plugged with nasty dirt powder.. Check your fuel rail for some nasty dirt powder,and pulse the injectors and back flush them out.
This was on my 07

Yes you do.
when Replacing the cam Sensors, You HAVE to Relearn them.[/QUOTE
there is only one cam sensor you dont need to relearn when you replace it the crank it is supposed to have a relearn now plenty of people have replaced the crank sensor and not had to do a relearn the only time you need to do a relearn is if it is throwing the code for it

TLDR. All ima say is u need thre3 things to make an engine wang. suck, squeeze, bang, and blow. you aint got one of those bitche$ and the $hit aint nakin powA. Put some redline oil in itl, and just throttle through the misfire. I would also put some platinum plugs in it to make sure that max boost is hit before knock retard.
