On some cars it there might be a need to tweak the chip a little. I do my own chips so that's not been a concern for me. I've heard of folks running Trashers, and Extenders without a hitch.
The biggie is that the late MAFs do their own temp corrections, so you can 0 out the MAF/IAT corrections. Then if you relocate the IAT to the plenum, and figure out the Timing MAT table, you have the utmost in a chip that compensates for all climates/conditions. No more detonation due to low or high MAT temps..
The down side is the it does take some work, just another goodie, that's not a 3 min modification. And you need to be more carefull about the uppipe so it doesn't blow off.
Another goodie is that the turbo is designed as a pressure pump, and it does a lousy job of drawing in air. With the turbo on the pressure side of the turbo, it's not longer as much of a restriction.
Which means if your trying to get by with too small of injector, it just makes matters worse since the engine is trying to make a few more ponies, and that means needing more fuel.
