ok first one - the dip - nothing to do with the nitrous, i get it on the normal run also - its due to a certain amount of cam overlap at that point where my cams are switching from about 230deg to about 290deg... this will be sorted with some pulleys eventually. i guess its just more evident with the nitrous on. so, nothing to do with lack of controller
why it drops off at higher revs - my bottle was almost empty and pressure was quite low. this is going to be addressed with a heater and a refill
thirdly - torque curves, yeah here you go. notice the same cam overlap exists tho

dip or no dip, and eith it dropping at higher rpm, it feels fantastic!
