Rev up your ride with this transmission module!

This Automotive transmission module is a game-changer. It has improved my car`s shifting patterns and the overall performance.The installation was also a breeze, and i didn't have to spend hours under the hood. The only con is that it's a bit pricey, but in my opinion, it's worth every penny..

Pros
  • Improved fuel efficiency and smoother shifting
Cons
  • Only compatible with certain vehicle makes and models

Get this inkjet chip - Engine Computers

Since the introduction of ethanol in the petrol we buy my 94 F250 has lost performance. I thought this might help and it did. While driving I noticed more low throttle torque, smoother starts and idle. A plus of 3 liters in the city and about 2 liters on the highway. It downshifts faster and holds the gears longer. The maximum speed is 300 rpm higher. If you want to give your old truck some power back, this chip is worth it.

Pros
  • Provides up to a 25hp increase in power
Cons
  • I don't remember but there was something
