Yes we have a customer testing a setup but he did his own nozzle placement, we're just doing the electronics side and tuning at the moment.

Hey Terry I'm looking to stay conservative on my 19 comp due to warranty.......so I want the phone app control and super quick install and removal......so stage 1 wont work since theres no app control......can I install the jb4 with the basic two stage 1 tmap connectors and obd cable? And not use the other connectors?....map1 and 2 will work fine?

What's the main differences between map1 and 2 for daily street racing....which is more conservative and less stress on engine.....which will make more power?

Yes, of course. Many don't bother installing the EWG connectors as those are only required for higher boost levels. Without EWG connectors map1 is probably going to be the best bet.

- so whats the main difference in terms of performance map 1 vs absolute map2 22psi? map 1 will run about how much psi max? trying to figure out which will pull in more power whp? which will have more max boost....same 93 octane requirements or there is a benefit for octane booster?

- so I buy jb4, connect the two tmap cables and the obd and I can switch from map0/1/2 no issues? no issues with cables disconnected or there will be configs needed?...any downside....I will be able to log etc?

Map2 is designed around the EWG connections so without them you're probably better off staying on map1. But can always log both to confirm what is working best for you.

EWG connections are optional, if not installed you'll make less boost on absolute target maps like maps 2+. Map1 will be unaffected.

would running 93 plus octane booster make sense on map 1 or overkill? better for safety when driving hard?

How hard is it to run the OBD cable through the firewall on the F90 M5?

Took me 5 minutes my first time. You don't even need to take the bottom panel off.

From the top I pulled the little eye cover. Stuck a little coat hanger down and it came straight through. I taped the OBD and slowly pulled it up and through. Plugged the OBD on both sides and done!
