I have stillen gen 3 and tanabe rear axle mid pipe and y pipe, iwas wondering if getting the tune is worth it. I want HFC hut I don't want to ruin the exhaust sound cuz it sounds so damn good. So should I get the 700 dollar Osiris tuner? I am experiencing low rpm bog/lag due to the stillen gen 3. So if any1 out there has info PLEASE leave a comment.

 

????!???????

 

Does any1 know?

 

Bump....

 

You don't even have HFC... not worth it. You're not gonna see a huge difference in power.

 

Once you start modding you have to see it to the end to be completely satified imho or gain the benefits in this case. The uprev will fine tune you car and help in all aspects. You wouldn't get that much more hp/tq w/o hfc but atleast you'll have stable ride.
