At BluePrint Engines, we strive to make your LS swap as simple as possible. Our complete LS controller packages contain all components and the proper calibration to get your PSLS37630CTF, installed in your muscle car or truck and have you tearing up the streets in no time. We take a complete LS controller package, and we specially calibrate the ECU to the optimum tuning required for our LS 530 HP engine! We also leave the ECU unlocked so your dyno shop can further refine your tune after your swap is complete into your vehicle!
