Thanks again to everyone for the feed back.
Got the radiator back in, and the maintenance all buttoned up last week. So i started putting some miles on it again.
First of all the noise difference is amazing. I read a bunch of threads on here about how much quieter it was after the lash adjustment but I didn't really expect it to sound that much different. Idle and low rpm noise is drastically quieter.
I also didn't think I'd notice any performance difference, but there is no question that it boosts lower in the RPM range, and more specifically lower in the throttle input. When I push on the throttle there is almost always a reading on the boost gauge now, where before if I was just slightly on the throttle or just semi-coasting with no real work on the motor the boost would drop to 0.
The amount of boost it makes is different now too. Previously I have never seen the boost gauge go above 32psi.. I now see 35 and 37 if I push it... I have not ventured to WOT yet... I don't know if that's something I'll ever do.. well maybe..
However. there is one noticeable draw back. (imho and I know there are some that like this but I don't) It now throws smoke when I accelerate heavily.
I rarely ever in the past have seen any smoke out the tailpipe of this truck. Tuned, with edge and smarty I would have to work hard at the lagging of the motor to get smoke, and I don't do that. because I don't like it.....
but now it seems anytime I try to pass someone on the highway, or take off relatively quickly from a stop, it gives a noticeable poof of black smoke. once the turbo spools up it goes away, But this is new for me and I don't like it. (#grumpy-old-young-guy. )
Is this a side effect that people have had from a lash adjustment before?
EDIT: Quick note, I have the edge set to "disable until warm" which will not change any of the performance settings until the engine coolant temperature is up to temp. and while the yellow light is on - on the edge - the truck does not smoke its only after the edge comes out of "backdown" that the smoke happens. So it seems that the edge is causing it but I don't know why that would be different now than it was before? is this was cerberusiam was saying about the edge adding too much timing?
Maybe I should start a different thread for this one?
