@AJ Jacob you should not be dissapointed with these results. Every dyno is different if you scan through the threads lots of people have had different dyno results from tuned cars. Thats even with the same modifications / set up. Each car and dyno will throw slightly difference results- Fact. Differences of 10-30bhp happen more often than you might think on the same types of cars.
The thing to remember is the difference between your stock numbers and your MTM Cantronic install.
You posted your stock car @ 285 BHP and 401NM (296 lbs)
Your MTM you posted @ 341 BHP and 494NM
That is very much inline with what MTM quote- 59BHP and 70NM gains. So if you want to just look at the headline numbers you have a greater increase in torque.
These results also clarify that secand hand / used MTM-Cantronic boxes transfered from the same vehicle type ( ie Golf R/ S3/ Cupra R etc) DO NOT require recoding to physically work! Something which has been very much misrepresented / ill advised by certain people/ companies.
Enjoy your car, and dont worry about headline peak numbers.

Thanks jungle! Indeed the information that MTM boxes need to be recoded when bought used is very much untrue! Especially when it comes from the same engine or car model. I was informed the boxes would not work without recoding by certain companies which seems untrue now.
Also the previous dyno of 285bhp was from the previous owner jungle and that was WHP. Unfortunately due to lack of time I was unable to do a baseline, which I might do now to get a clear difference in performance.
