RKTuning is your home for Late Model GM Tuning. Our tuning support covers 1997+ GM LSx and LTx powered vehicles, LSx and LTx Swap vehicles, and aftermarket EFI Support for platforms such as Holley EFI, Haltech, MaxxECU, Fueltech, and more.
If you are local to the New Jersey Tri-State area or willing to travel we will bring you in for an in-person custom tune. Tuning is done on both our in-house Dyno as well as verified out on the road to ensure your vehicle performs and drives as well as it can.
RKTuning offers online email tuning services and support for shops and individual customers around the world. If you are looking for tuning but aren’t local to us, we can get you set up with a remote tuning package that includes tuning hardware, software, and any instruction needed to ensure a streamlined remote tuning experience with us.
We offer bench flashing services for common LSx and LTx Controllers including E92, E38, E67, P59, 411, and more. If you simply need a start up tune to get you going, or have performed a DOD/AFM delete on an otherwise mostly stock daily driver, send us in your PCM and we can get you up and running.
If you have questions or concerns about your existing tune or how your recently purchased vehicle is running, we offer tune and log review services to determine what the health of your vehicle is, help with diagnostics, and to determine if your tune is currently optimized.
We offer tuning and software training for shops via email or video conferencing as well.
RKTuning offers EFI Dyno and Street tuning for LSx, new LTx, and Standalone equipped vehicles. Conveniently located in Ocean County, New Jersey. Easy travel and access from New York, Pennsylvania, and Connecticut.
Remote Tuning with HPTuners available for Domestic and International Clients.
