mTune SMARTflash m235 Upgrade [Puma ST]

The M235 has transformed the Puma and made the driving experience absolutely brilliant thanks to the progressive nature of the map. This is how the Puma St should be and puts a big smile on your face. I cannot praise these guys enough as I’ve had other Mountune maps before and they deliver the best performance for your money. Great product.

Good product easy to instal

Tiny change - great result!

Mountune m235 Upgrade for Puma ST is a really balanced upgrade. You can definitely feel a substantial gain in torque and horsepower in the midrange rpm, but its extension to higher rpms is most enjoyable. In stock map you feel like there is a burst of acceleration and then it dies off. With m235 its held for much longer. Now revving over 5.5k really makes you smile and keep your right foot down. But at the same time it's not overdone at all. You still retain driveability and predictability of your Puma ST. For someone who wants OEM+ upgrade its a way to go. The only thing is that when you cruise at about 2k rpm and decide to accelerate there is this weird misfiring like sound. But that's due to cylinder deactivation and additional VDE deactivation software solves this issue completely and much of the vibration at idle also. I think m235 is really worth it and I recommend it for everyone looking for OEM+/balanced upgrade. Also the versatility of the app and the bluetooth programming kit - possibility to go back to stock map, performance and data logging, ability to add VDE deactivation or upgrade to m260 is great to have. Can't wait when the Induction Kit will be back in stock as well. Keep up the good work Mountune!
