    Gems Chip

    Posted by Thomas M Mitchell on 27th Mar 2025

    w I installed the Gems Standard Chip Set into my 1998 RR P-38 right after I received them. I am on my second engine with only 56,000 miles on it. I am the original owner of my Rover bought in Oct. 98 from Peabody Ma. I have always taken care of it but unfortunately the engines had a bad rep. and it happened to me. The car now has 175,000 on it an with the Gems Chipset it runs fantastic. I immediately noticed better throttle response, more power and smoothness at the low end I have just mounted the carbon fiber trumpets and noticed even more power and smoothness. Thank You TWS, Tom.
