Well I've had the kit hooked up for two days now and it's workin great. I have the 65 jets in and made a couple runs and checked the plugs and everythings cool. I'll be putting in the 75 jets next week. But for the older eclipses that can use this kit I highly recommend it. It took me about 3 hours to hook it all up and that was by myself taking breaks. I'm on the hunt now for some cars to kill and i'll try to get to the track soon and post some times.
