Bummer. I don't think I have a leak from what I could see. Stock I can only hit about 20lbs unloaded and 25lbs with srl tune. Also previous owner did egr ****** used puck in uppipe but read that may be OK due to early design. I think I may try and replace uppipes with bd power and maybe add a wicked wheel. I've noticed it was leggy from day 1 but was comparing it to an 04 excursion I drove and now the 05 confirmed there was a difference. Where does your stage 2 fall in regards to lag compared to the 03, 04 and 05-07 turbos?
I mean this in the best possible way. But you don't know if you have a boost/exhaust leak unless you actually test it. People always doubt that they have a leak, even though just about every truck I have tested ended up having some sort of leak. Don't just throw parts at it. Take 20 min and do a boost leak and exhaust leak test, it might save you a lot of time and headache.
I spend A LOT OF TIME working through problems with people, they describe high egts, turbo lag, and low boost. It seriously make me laugh when someone says "wouldn't I notice a leak"... well I think you are noticing a leak, that is exactly what you are describing.
The stage 2 turbos spool very well. Many report faster than stock with the right tuning. But I try not to sell people turbos when they are complaining of major turbo lag on their stock setup, because these stock turbos should not be super laggy. It is usually a sign of an underlying problem that does not get fixed when they swap the turbo.
