I have a 2016 RC 300AWD F with a certified warranty that I am wondering about upgrading. I see chip-sets that claim to increase HP and gas mileage without affecting warranty. Anyone have any experience with this? I have been told that he engine in my car is the same as the RC350 is this true.

Thanks Chas

 

Yes, it is the same motor as the 350, but dont bother with those "chips" Get a real track proven tune from RRRacing. They have the perfect tune that will take your 300 and tune it to that of a tuned 350 motor.

 

Thanks for the reply I will look at this company.

I would agree. Go with a proven company. I have the RR tune and it is great.
