Transmission and ECU tuning question

alright guys, ordered the following parts,

Stage6 performance variator
Stage6 pulley (kickstart only style)
new kickstart shaft
new kickstart spring
lock nut washer (for kickstart)
kevlatr drive belt
new variator caasing bolts
new kickstart lever
new mirror
oh and a cdi unit that will get rid of the rev limiter.

was just wondering how the set up would work, it comes with 6.5g rollerrs ( sounds a bit heavy to me?) and a 'medium' contrast spring.
will these go well with my leo vince TT exhaust?

also if i put the unrestricted cdi on, what are the pros and cons, and is there danger of blowing the engine?

thanks.

 

the unrestricted cdi isn't really neccasary

 

will it make a difference?

 

Nope, your standard CDI is NOT restricted anyway, it just retards the ignition at very high rpm, your engine will not rev that high with the specs you've got. Its only worth doing if your engine is capable of 14,000rpm++
