CP-E guys are for real... this is why
I know this is an old topic, but I just joined the board and wanted to reassure everyone here, that CP-E is the real deal. I just traded my Mazda6s V6 in for my '05 4runner. I purchased their intake and mafci kit. It seriously made a difference in the performance of the car. So much in fact, that the stock wishbone engine mount on the engine snapped from the added torque. I never had my car officially dynoed before or after, but it was a enough of an increase in performance that I needed no convincing. The install was very easy. The mafci attached to the stock ecu via tapping into the wire harness. I have no electrical background and installed it easily. You have the option to use Scotchlocks or soldering. Best of all, no check engine light codes were thrown compared to competing companies like AEM and Injen.
I would highly recommend any of you who are interested in increasing the performance of their 4runner, V8 and V6 included, to donate their car to CP-E. If I lived closer, I would donate my 4runner for testing.
I would also like to mention that for being a smaller company, CP-E has terrific customer service. If you have problems or questions with the product, they are more than willing to help satisfy.
My two cents...
