I first ordered the edge evo cs for my 97 OBS and I was seriously disappointed with the transmission tunes. They just held the gears too long. It was somewhat annoying to daily drive. I was about ready to send it back. Then I found PHP (sounds sort of like finding Jesus or something... well... it was a sort of similar experience
Ordered the custom calibrations. Then waited. Sometimes patiently... Othertimes not so patiently. Then once they arrived. WOW!!! I am in love. Just my $.02... I would just order from PHP the first time.
