not really without other mods such as a full exhuast system etc.

Let me know if you want one of these. I can now supply them..

Won't make a diffrence to the CG10. I had one on it and couldn't notice anything on it.

Needed if your using the 1.6tb and ECU as you can help set Idle.

if i had full exhaust system what gain would you expect??
its a cg10

how much can you supply for ed?
