Hello everyone, i'm installing a charge pipe, intake, intercooler this weekend. I also already have a remus exhast axleback on. I'm planning on installing a JB4 but I have no plans for a downpipe. What map should I run? I read you needa go catless for map 2 but I can't find anywhere about being FBO without a DP.

Map Guide as of v15+ firmware:

Map0: Stock tuning, fully disable JB4
Map1: Additive map with peak of 3psi over stock added (91 octane)
Map2: Additive map with peak of 4psi over stock added (91-93 octane)
Map3: Additive map with peak of 6psi over stock added (93+ octane)
Map4: Absolute target map with peak of 20psi target (93+ and/or E30 octane) suggested for higher boost models like G chassis, Supra, and Z4. EWG required for proper control.
Map5: Absolute target map with peak of 22psi target (E30+ fuel) suggested for higher boost models like G chassis, Supra, and Z4. EWG required for proper control.
Map6: Custom tuning map allowing both additive (below 10psi) and absolute (above 10psi) targeting. Setting RPM1500 boost below 5.7psi will make entire map6 additive, setting above 6psi will make entire map6 absolute target.
Map7: WMI map (boost varies based on WMI additive, meth flow, and other criteria)
Map8: VALET / Low Boost Map
