Thanks, I think that's what I'll end up going with eventually. The leak has stopped, but it's not a very clean fix like that is.
The updated tune has made the truck a monster. It's currently doing 0-60 in about 10 seconds when stabbed from a stop, not brake boosted. It's a little smokey in the low end but that's alright, the turbo lights very quickly and clears up the soot in a respectable time. EGTs are fairly low for the most part, they level off around 1000* at WOT once it kicks into 3rd gear, and the truck pulls VERY hard everywhere in the rev range. It's a very nice change from what I was running before. Overall, I'm a highly satisfied customer.
