I've been running the upgraded turbos from ATP for well over 1 month now, and I have not retuned..... yet.
However, it goes w/o saying, that by electing to not retune, your essentially throwing your money away by paying for the hardware upgrades, w/o benefiting from the software upgrades.
In my case, I don't care to be chasing down, what amounts to be anticipated boost leaks (when I do retune) therefore.....
I am holding off on doing so (for now) until my hard/hot pipe order arrives.
Once installed, I then anticipate making the 5hr trek back out to LMS, for (yet another) custom dyno tune file.
At this point, & factoring in the multiple, upcoming Holiday's, I probably won't schedule the new tune until January 2014. If the weather's crappy, which it is usually is in MI. during the Winter months, then I may push it back into February.
But for now, I am still running my "old" custom dyno tune file from LMS, which has been working just fine thus far.
