I don't have it on my truck but from what I hear the gains are nothing spectacular. It does make the turbo a little louder on the intake side and slightly faster spool up. I'm sure mackyoudip or someone will chime in and help you out.
call and talk to larry at danville performance...he can tell you what kinda gains they are seeing...i talked with him about one on an lb7 with efi live, and im sold on it.. just gotta let the account build back up cause i just dropped over a grand on airdog 2 and insite. if i were you i would spend money on gettn the fuel and filter system upgraded first....well after you get a truck that is
I have one on my lbz, I installed it at the same time as a egr delete,3" down pipe and LML manifold.
The truck is on stock tune for now with just the egr and grid heater deleted, and the truck runs better, has a bit more power and spools faster.
But I agree, if you have to take the turbo off then do it for sure, I had a oil leak from the pressure line under the turbo so that's why I did it.
And the sound, well it sounds like super charger whine now lol.
I have one on my LBZ, it really helped my spool up, also I have zero smoke now on every tune except my big one. I did it at the same time as an EGR delete, so not much more work.
Mine suprisingly cleans up my 40 over nozzles on my tunes as well. I like it so far. If your worried about making your stock charger last forever, just know that these are unproven for reliability so far. (the balancing controversy)
