If you are getting the smell of diesel fumes and are losing boost it is more likely your up-pipes are leaking...

Wiff of diesel in the cab... Start with the up pipes. Look for black soot around the top of the pipe where they enter the collector. A little mirror and a flash light helps with this. Make sure all the IC boots are tight. Take a look a the turbine wheel as well. Should have nice clean sharp edges. Got a clean air filter?
Good luck with it. You'll find the culrpit.

Izzy has pictures of how to build one. But I would focus on your up-pipes because your not going to get fumes from a intake boost leak.

Here's a 3" PVC cap drilled & tapped for an air nipple. All it takes is a 7/16ths drill bit, 1/4 NPT tap, and some teflon tape around the nipple. You might want to scuff up or put a couple small screws around the edge of the cap to give the intake something to bite into so it doesn't fly off... It's amazing how much force just 20-25psi puts on that thing.

The spools faster/sounds louder, which are pretty subjective, are on the drive side of the boost, which you will not be able to see with a leak detector. The leak detector will only showl leaks past the turbine. If your uppies are good - check the other things that make boost - turbine wheel condition, air filter restriction. Are you getting coal to the fire? fuel filter, fuel pressure.
Do you have a Boost gage? What sort of readings are you seeing...
Are you really sure you have a problem, or is it just that it seems different than your pop's truck. Different intakes make different sounds, and sound is hugely subjective.
Best of luck.
