Sorry but I have had a quick search and I am still confused as to derestriction of my MC28SP, splices, HRC cards etc etc.

I thought I just had to change the exhausts - the main tuning restriction, and have the wire splice to get a healthy 55 BHP or so. What does the wire splice do?

Do I loose the digital display with a wire splice???

Do I have to make any further electronic changes to optimise the bike. I don't want to tune the bike any further than fitting race exhausts, ie. compression, porting, ignition etc will all be left as standard.

Am I wrong to expect ~55BHP from a standard engine with a race exhaust?

The previous owner said the bike was ~57BHP but had no supporting evidence. The bike will pull well past where the speedo stops at 180 KPH and I reckon I've had it up to ~195-200 KPH so it must be >45BHP right?
