R35 GTR Performance packages

[ACspeedtech]

ACspeedtech have the experience of tuning the GTR, developing premium products and selecting the best available parts since the first GTR was imported in 2008. Tuned using the COBB custom ProTUNER software with many hours of dyno testing to develop the base calibrations and mapping principles that work best with the VR38DETT and our selected components.
