ok here some infos about increasing t135fi power i have searched them and i can tell u exact what u need ...
first of all u need to buy a paralel(dont know how its spelled) ecu its like u having 2 cdi's on that ecu u put with the help of a pc 3 maps 1 map for low power 1 for medium power and one for high power the bad things is that the t135fi is new in the market and there are no free available maps so u need to make by yourself in that case u have to go on a ecu programmer and put your ride on a dyno and create 3 maps but those 3 maps will work only with the corrent things u have on the ride for example if u change exhaust different than the one on the map it wont work good so u have to go and make one more map that all about the fi i hope i gave u some answers
btw that ecu its udjustable u push the button u want for example long trip?? push the low button want to do wheelies??

push medium button want to drag race push the high button
