* If you are prepared to use 98 octane fuel (not essential, but best to get the maximum performance) - you can enjoy the performance that your car is actually capable of. Power gains are anything from 10-25bhp (often more) with torque gains of 15-22lbft. NOTE: All power and torque gains are dependent on your car's current engine condition, modifications and induction systems. Power gains can not be guaranteed.

Some customer comments.

"I have just fitted the Promax chip, bought from and with fitting assistance from Stuart ( thank you Stu) First impressions are, the car feels smoother, less torque step around the 4K rev range. The car feels younger and smoother in its drivability. The whole experience is more linear, not sure that it is faster but the car has an subtle urgency about it. When I have had it in for a week I will report more. First impressions are very good and to be recommended."

Fitted the Promax chip along with the K&N filter on Saturday and took it out for its first blast this evening. It does seem to go well and top end breathing is way better. I didn't hit the limiter but it feels like it wants to just keep going. Definately feels quicker.
