on the digital tuning web page they are a side by side comparison of the 1.5,1.7 and 2.0 well it stats that for the 1.7 550cc is minimum inj. size but can you run bigger like 680 cc or 720 cc ??? just wondering if poss.. and the effects if i did do that

 

nevermind it says that it will run to rich if anything bigger than 550 cc primaries without afc

 

get the 1.8 you can run 4 x 720cc

 

too late
