IMO the BT cable is a must if you're running a modified n54 (except JB4 users) as you need be able to investigate any issues if they come up. It's a shame that I bought a second hand one with only one VIN number left as I'm up Manchester quite often.
It might take a few days to fully adapt, how many miles have you covered since the reset?
I plan on keeping the car for another coupe of years at least so maybe it will be a good investment to get one anyway as you say.
Did you follow mr5s to the letter and re-set all the below with engine switched off?
Air Control Adjustment
Throttle Valve Adaptation
Secondary Air Injection Adaptation
Its also important to run the car at between 2 2.5k for 5 mins and then leave to idle for 5 mins after the reset. Did you do this?
