Anyone know what the deal is with these Greddy spec turbo chips going arround. What all does it control? I know that vtec engages@5100, Redline@9000, but is that it. Will it actually read boost from your map sensor and give the according fuel, is it just an "internal" version of their blue box? I got one on order just watin for it to come, any info would be great.

 

No, they are a joke..
