ACPT from US also makes them. I believe nismo's are made by them if my memories serves me right. and they are much cheaper than Torqline. Googled extensively last year cuz considering one and it shows that these things are a worthy upgrade though most of the people never knew such things exist.
Not sure about Nismo, but I think ACPT make for Trust/Greddy. Not sure if its cheaper if you buy direct from ACPT, but it is sure more expensive to buy from Trust:confused_smile: How much is it from ACPT BTW???
As for Nismo, do they sell them or just for their Z-tunes only???
