we've been doing the socketing and eprom upgrades since 1994.. That time we started with the Infiniti Q45. Since then we've done hundreds of 300zx's Twinturbos and NAs. Our stage III chip made 400rwhp and our best has made over 840rwhp. Easy to install and if your ECU isn't socketed we do that too.
Upgrade Eprom just $60 includes shipping back to you.. Fuel and Ignition maps modified, rpm limiter rasied, mph limiter removed.
ECU socketing just $60
And If you just need a new ECU socketed $150
We also do 16 bit ECU upgrades.. The competition just installs a PCB board with no capabilities to change anything once it's installed. Ours has the features of being able to do diagnostics and the ability to change injector size, and modify the fuel and ignition maps $399
