John and Kevin. I want to congradulate you guys on this system. We have now drove the first EPA version over 1000 miles without even the slightest hickup. This car is going to be a real hit on the market. We have seen remarkable fuel milage on the high way. We will delivering this vehicle to the customer next week with a big press release from the new owner.

The car has great cold start, great acceleration, very good range. It is absolutly unnoticable that you are driving a NGV ( like it should be).

We look forward to installing these system on new cars as they come in.

I dont normally indorce a system this early but so far we have had a great experince with this system.

If any one has any questions and wants a real answer from the techs that installed the system call TGT and ask for Chris.

Keep up the good work
