Have you got a USB cable connected? Easiest way to check is connecting it to the JB4 interface and looking in the specific menu. The fact it is auto shouldn't make much of a difference once you are moving.

Turn on gauge hijacking so you can see boost on the dash board (fuel gauge is my preferred position). With your mods, I'd expect to be hitting 15-16psi.
Ensure the car is warmed up, JB4 will target stock boost until up to a safe temperature. Mine take 5 or 6 miles to reach this temperature.. I have activated the flash hazards on warm up option.

With those mods OP you should be manically wheelspinning into oblivion if you're flat out in 1st and 2nd, i can't even pass 1/4 throttle in the damp/wet without spinning up.
When you say 'quick off the line' I hope you have DTC on, if you haven't pressed the DTC button, then traction control will be raining it all in and making it very 'normal' (often without flashing the tell tale light) Try DTC short press (you can set the JB4 to automatically do that for you). I always run with DTC on, really takes the shackles off the motor. Also remember oil has to be warm before JB4 will give higher than stock boost (you can set the JB4 to flash your dash indicator lamps to tell you when the oil is warm enough) |

That is about 105 European Octane (RON) V power is only 99RON, so way short of the 105 minimum for map 7. |

Does it hold 14.5psi? You could also guage hijack "under/over boost" on the oil guage. If you are under or over target likely to be a boost leak, vacuum or wastegate issue. Also put all the jb4 settings back to standard (as per n54 tech) and reset adaptions.. Did you read up on the open fuel loop mapping issue?

Ah but you haven't managed to connect a laptop. You need to do this to see how it's currently setup. Can't see why you would have trouble connecting, is it a com port issue?
