Also, if it helps put it in perspective. I currently run a catted JDL UEL (that’s gutted), with a JDL catless/resonated FP w/ my JRSC. On Friday, I’ll be swapping to the PTuning Race Header and JDL UQFP and will be retuning to account for the new cat and well as the flow differences between the UEL and EL.
