I went with the Techco. At the time the E-force was just comming out and the first install was having a problem which turned out to be a bad spark plug. I liked the fact that Techco manufactured every part, was a twin screw with 3L flow, had a front intake with an air/water intercooler with very low intake temps. Their kit was complete and straight forward to install. The promise was great...I took a huge gulp when they went out of business a few months later. If I knew then what I know now I most likley would have gone with the E-Force. Two years later there have been no problems. knock on wood. GA
