[Shotimes] Hypertech Chip

[DAVE]

Anyone have any good data on the Hypertech Module? I finally got around to checking to see what was installed by the PO and it's a Hypertech 600421. But the Hypertech site is pretty vauge on the whole matter.Just wondering what performance gain it really has. Seat of the pants it's ok. I've made a run without it my secondary runners kick in at 4000 where they were kicking in about 3500 with the chip installed.
