After a few email chats with bluesparks Ed....I finally ordered the 3 channel Pro box with Bluetooth since no one on here has this version or with the Bluetooth , I thought I'll keep a record of it here
So the car is 70th Pista, 165bhp , Garret turbo with monza active exhaust , 21000 on the clock.
ordered last night.....and my pal is fitting it next week because I can't be trusted

Happy to say the forum 10% discount still works....

Fitted today
Bluetooth mode said it was set on C6....
1st run....it doesn't feel no different
Changed the settings to A6....still doesn't feel any difference
From reading others experiences they say it takes a quite a few miles for the unit to get use to the car

I'll let you know

☆☆Edd recommended that I don't go above C6☆☆

Excellent news

Now I've done a few miles with it.....its really noticeable in normal mode, everything feels better and way more powerful  , I would guesstimate about 15-25% more powerful.
In sports.....fook me its bat sheet crazy fast.
The 3 channel is different to the 2 channel version

The 2 channel box , you change the modes to get more power.
The 3 channel is way more refined,  you don't need to change the channels unless you add performance parts , then you have a word with the bluespark guys and they will advise you.

In all I'm VERY happy with my box, it changes the car from great to raging bull.
Bluespark told me in C6 mode my car should give between 190 to 200hp....
