It has been over five years since we first tuned and supercharged the Lexus RCF, and we are very grateful for all the support we received from the Lexus RCF community over the years!

We decided to use this opportunity to perform the most transparent and thorough testing of RCF mods. This was especially revealing given the recent trend with some tuners who have released grandiose claims (of up 20-30 hp gains!) by playing tricks with Dyno testing, showing unrealistically low baseline dyno results, and in general advertising dyno results with very little clarity or transparency in what was done.
