Thanks for sharing, I like it. Hope the fitment is decent. Also can't justify >500 when it gets bashed up on my own driveway.

FF is saved per map, so save it to whatever map you intend to use. Should allow down to like 21-22 psi minimum, maybe it is an app glitch

Try Map 1 at FF 30 first. car is stock?

boost control isnt bad, you can add a bit more duty to 3500 to fix that torque dip, but otherwise your main issue is lack of octane. Good bit of timing corrections you can try IAT spoofing higher to see if that lowers the base timing, like 130. or any ethanol/octane booster at all would fix it.

usually don't need to adjust duty bias at all with a stock downpipe. Sometimes small changes can help but rarely are there big throttle closures that affect drivability.

Theres really no difference to lowering FF vs lowering all duty bias, its just quicker. Its best to set FF based on my recommendations in the first post, dependent on downpipe. I spent the time figuring out those ideal ranges to isolate that variable so you guys can just focus on duty bias for...

You can try setting FF to 40 to see if it'll bring boost down some and timing will improve. at that IAT, you don't really want ecu_psi >16

User adjustment - advanced. I just said to turn it down due to the throttle closure

Depends who tunes the Jb4 ;) You aren't wrong that MHD is smoother out of the box, but a properly tuned JB4 should drive as smooth as stock

Looks fine, may benefit from FF at 25

@mustafazumit has tons of issues with his, and filling up fast with DAW ultraflow X at 30 psi

FF is multiplied by duty to set the actual wastegate position during a pull. both ranges are 0-100 rarely does FF go higher than 60 even on stock DP, you will max the turbo 70+

yeah you are good to go until your custom map, throttle closure isnt that bad but you could drop duty4000 and under by 5 or so to clean it up

I'd just drop everything duty4000 and below by 5 and see if it cleans up since there are a lot of cuts

Except for FF is map specific, so make sure to set that after switching to intended map. only difference for map 6 vs any other preset map is boost targets. @mk5.matt

catless? Use the recommended settings in the first post based on the DP on the car

completely agree, no one looks at the car from its awkward angle. That's why everyone says it looks better in person.

honestly I could see myself replacing the GTI with an alltrack for more practicality. 7.5 is peak, wish they still made them at all. IS38 alltrack is a proper sleeper too

you can tell it is TC rather than MT stutter because timing will drop abruptly with TC but not the "MT injection monitoring" also you can see wheelspin in the rpm curve

I've already picked up 2 things this week that would not fit in a sedan but fit in the GTI. Hatchback is a replacement for a crossover, and it looks far better than almost any of them (and performs better, better mpg, better dynamics, etc)
