I have a UniChip. They are an ok computer for minimal mods. If I was to redo the computer I would go for a VERSO tune, though don't know if they are avilable for the GC8.
If you do end up getting a UniChip, go see Tim Slako at West Racing. He's a pretty damn good UniChip tuner and knows what he is doing. I think a few of the guys on here have had their UniChip's tuned by him, including myself.
I've got 274 PS (201.5 kw) at the hubs with the UniChip (On the ASG dyno) with simple mods. 3"
tbe and air pod, running at 1.3 bar max.
