Im in the same boat bought it last year and have done alot of tunning but want more power. It doesnt really have the "snap" i want to i look at it this way though for the $4000 i paid for the sled (imported out of the us in mint shape) and then the $1000 i just spent to fix the a-arm and shock and do a few other little things and maintenance, i have $5000 into it. So i said to myself i see twin pipes and fuel controllers for $400-$700 all the time so ill pick those up and then it would have more power and be lighter then a m8 and i doubt im going to find a mint m8 for $5500 plus i wont know it like i do mine and its more of a hassle and all. What do you think ? What do you have done to your sled ? Hope this helps you and all.
