I know he has not responded yet, but the piggy back tunes effectively use the stock tune and fool it by changing the inputs from the MAF sensors. This can be somewhat less predictable, especially moving from lean cruise mode to full throttle (the 60-130 results). A full tune has timing, fuel, air and other supporting changes that will consistently deliver the same results. He is getting similar results that I saw with a move from a Racechip to a full ECU tune (EVOMS).
Did your racechip have the same issues? after some googling it seems everyone is happy with these piggy backs at first, and then they start to crap out.

Over time, the computer tries to compensate and I believe this ends up affecting the results. The initial results tend to fade away. I also found the drive ability of the full flash tune much better. You would never know it was not stock until you put the pedal down. Well worth the investment along with an IPD plenum and air filter.
Well boys we are officially ECU Tuned. Who did I go with
the fine people at DME brought me into their offices which are local to me and bench flashed my ECU. Guys, the car feels so clean and all the drivability is like stock. In addition the way the boost comes in is smooth and it holds that boost throughout the rev range.
So the question is, is it faster than the chipwerke piggy back? Driving the car, it is hard to tell if there is more power or not. So I went to the vbox (my dragy died) to get the data i needed. It is too cold in the northeast for dig runs to test 0 to 60 or 1/4 mile, so my only test I can do is 60 - 130 mph.
My previous best is 9.05 seconds however I couldnt seem to ever hit that time again. Consistently the car was closer to 9.3 seconds.
Well now boys and girls we are consistently a 8.9 second 60 - 130mph car with 8.8 seconds being my best so far.
This proves that not only is the car faster, it's more consistently so. I look forward to heading back to the drag strip with some good prep and on full race gas. I think I see 10.9x in my future but we will see.....
did you ever get the 0-60 and 1/4 mile times? (On the street). I looked through your channel and didn't see anything posted (and I am subscribed lol). Just curious to see how much of a difference the downpipes had, and your trap speed
