That said the before and after results here still show a large improvement. The stock 0-100 time times shows 10.3 seconds. With the addition of the Renntech Stage I tune only this drops to 8.8 seconds. That is a significant difference in acceleration.
1/4 mile numbers go from 12.9 @ 112.1 stock to 12.1 @ 117.6 with the Stage I tune. Another large difference and the trap speed difference of 5 miles per hour between stock and tuned would likely be closer to four on the drag strip. Regardless, this tune is showing a large difference in performance using the same testing hardware and that is what is important to notice.
It is becoming increasingly evident that with bolt ons and race gas the M133 motor looks like it will be capable of 11 second 1/4 mile performance. For a factory 2.0 liter four-cylinder on the stock turbo and motor that is excellent performance.
