6.0 very low boost after i did egr delete and exhaust

HI,
I just installed an egr delete kit and exhaust on my 05 6.0. after putting it all back together i had a hell of a time getting it to start, i did not un hook and fuel related items. it would crank but no smoke at all. it has done this 3 times in the past but always started after several cranking cycles. this time i gave her a very very small snort of ether and it started and has started several times since than no problem, both when it has been cold or warm. my other issue is i cannot get any higher boost than about 8lb. i took the turbo back off and ripped it apart and cleaned everything and it seems to all move freely. it is back together and still the same issue, might even be a little worse. what should i look for next? i hate to take it to the garage, i have always done all my own work and all the new electronics are driving me nuts!! any help would be greatly appreciated.
Thanks,
Chuck

exhuast leak somewhere... look for black soot traces on your firewall and you know where it is.
Make sure that when you connect the turbo the flanges are tight together. The clamps WILL NOT bring the flanges together when tightening!

This might sound crazy but is your vgt solenoid plugged in?

Do you have any king of gauges or scanner? If you do you can look at the vgt duty cycle to see if its working

Thanks for your help guys, i found the problem this morning, it was the 1/4 inch line from the intake to the sensor that operates the vgt. i must have bumped it while doing the other work, it had a very tiny crack in it, she is good to go now and the mileage went up almost 3 mpg in town!! Thanks again
