Welcome to all

I am confused between the intercooler from R&D R5 @ RIVA Power Cooler Kit ?
Where I will catch the E 1 and ECU alter the use of SHO Powershot Adjustable Fuel Tuner , and from Roeriys Giebn to this question, ECU Roeriys Do I need to be reprogrammed on all the pieces are installed, that my FZR naw is riva Stage 1 kit wath FZR Sponson Kit R&D , R&D Engine/Intercooler Cooling Kit R&D, 74,8 MPH 7500RPM
Now I will buy
1- Power Cooler Kit from RIVA OR R5 from R&D ? After your advice >>>>
2- E1 Impeller Supercharger .
3- Supercharger Shaft.
4- Solas DynaFly 13/25 or 13/24 ? After your advice >>>>
6- Upgrade Kit, Valve Train .

Any advice

With my thanks and my respect for your reply
