studs injectors and now a noise

[ssb541]

i just did injectors, head studs and egr delete in the driveway with the cab on. eric sent me new tunes and it runs awesome but when i was pulling a grade i put the pedal down and right at 30lbs of boost i heard an air noise like fast short whistle blows and the boost gauges starts fluttering but i am not loosing any coolant and it's not puking. any ideas, thanks.

did your EGTs go up??

i don't think so

i would check to see if any of your boots came off or are damaged and its a boost leak your hearing.

Might want to check your up pipes and up pipe connections to the turbo and be sure there is proper torque on all the fittings...

could a cracked up pipe make that noise

it could... but i doubt that is the problem

i have tried to get it to do it on flat ground but i can only build like 28lbs of boost i have pull a grade to hit 30lbs and that is when it starts

i would check all the boots (easiest to do) just start eliminating possibilities

but your not thinking head gasket
