My 2 cents = you've tried a different prob same thing and different tunes same thing, going to say it's not prob or tunes.....

Thanks guys for the support and the reccomend at becoming a sponsor. As fate would have it i've already been in talks with AutoGuide about combined pricing for this forum and CF since I am on there.
In short - I feel bad that I haven't been able to help Matt. He is going through the valves and adjusting them again and in the process i've requested he send back the injectors so I can have them tested on the flow bench and in the Bosch test stand itself at II. I know lots of guys don't like them, however they have treated me and all my customers great. I like that i can personally walk in a CP3, a set of injectors, etc and WATCH them be tested and get the printout right from the Bosch test stand on each injector, if it's balanced, it's return rate, etc.... and have them tested however i want at whatever pressures I want all the way up to 28k... Not trying to change any minds here, just saying that they've had their growing pains like many places and I feel confident if it's an injector issue we're going to find it - or rule it out since he has them out anyways. Being able to watch it tested also means there's not much chance of getting BS'd too - another reason I like the setup.
I try my best for all my customers, regardless of who's parts or what setup they're using - but i've had a couple trucks that just kick my backside in the end and I can't solve the problems for them. I hate when it happens. I didn't take offense to anything in the thread - there has been lots of great discussion so far in the thread (ideas and such) - and like I said in my original post. I make mistakes too. One way or the other, I hope we can get his truck to where it should be and close this thread on a positive note.
That being said, anyone that has additional ideas or input for him or for me - feel free to fire away! I'm continually learning and trying to improve.... so please keep any ideas coming!

I custom tune all kinds of stuff and try to make them go faster, breath better, and play nice.
When in doubt, 0xFFF it out

Zach, you are definitely going about it the right way IMHO. When you have an issue like this where it doesn't respond as you would expect then I've always found it helpful to methodically recheck all the systems. I definitely think it was helpful to bench check all the injectors (doesn't matter what brand you're using, test results will tell you one way or another) and then to double check valve clearances. An overall compression test would also be helpful to know the mechanical systems are working as they should be. It would be nice to also have some verification that the timing gear on the cam was installed and lined up properly. Beyond that it would be good to pressurize the intake and double check it all for any possible boost leaks (I would use 5psi more than the max pressure that turbo will see.......it would be good to use the KENT-MOORE J-46091-15 adapter for the test). Next I would have a look at both the baro and MAP sensors to check they aren't plugged/damaged and that the signal they are sending is correct. Finally I would sweep the turbo vanes to makes sure you're getting full movement (0-100%). If all these check out then it's time to start digging a bit deeper.
Hope this helps.

Injectors appear to be the culprit - still waiting for a final verdict tomorrow - but looks like there's a problem with them when they were tested in the Bosch machine - but i'm not going to pretend to be an injector expert - I only know they weren't happy with the results and are tearing each one down to go through them.
The tips ended up being 45% tips as well. Not a huge difference, but not exactly what the tuning was aimed at so.... a few compounding problems but I think this will be the ticket to getting his truck right.
We will definitely post up the results once everything is back together and running.
