Okay, so it may look like a steep price to pay but overall it has smoothed out the rev range and seems a bit pokier at 3k RPM, with those adjustments I should see a slight uptick in MPG as well according to the computers MPG calculations.
Well, it is not a revolution and I didn’t expect it to be but, the MP135 does make a really nice and easy difference. Together with the panel filter driving is more smooth and relaxed. When accelerating you feel the increased power from about 3.000 rpm. Installing went brilliantly. I was nervous but, 5 minutes and everything was settled and it was plug and play. The set is worth the money and Mountune has done a good job on this one.
