Custom tune on JB4 help please

[ScorpionStingz]

So I was told I should get a custom map6 JB4 tune on my stinger since it’s been modified quite a bit. I’m more than happy with the power output of map 2. But someone mentioned a custom tune to deliver similar power to map 2 will be beneficial?
These are what I’ve done.
- MBRP cat back
- MBRP resonators
- snorkel air intake
- injen CAI
- HKS spark plugs and BOV
- ADD dual catch can
- HFC downpipe and catless secondaries diameters increased to 2.5in
- JB4 with wastegate adapter
- swapped out the X pipe for an H pipe.
- mishimoto intercooler
- BMS transmission cooler
- BMS diff brace
- replaced stock brake pads
- engine oil cooler with secondary radiator.

You don't need a map 6.

You definitely don't need a map 6. The only thing somewhat unique is the downpipes, but if you have the car running reliably on map 2 then you don't need to do anything else.

It's not like they will ever build these cars again. Have fun!

Be safe tho

If you want more, go for Ek1 and the ECU tune. That will make a difference!!

If your map tapers at 15 you can add more boost with higher octane fuel to make it taper at 17 at high rpm for example a map 6 needs better fuel
