1. How much does it cost? 2. What kind of performance upgrades could I expect?

 

Sorry, No one is going to Dyno Tune an IS-F....

So it should cost you ZERO

Didn't know. I am far from a mechanic, so I am trying to learn as I go here. I hear about guys "tuning" their rides and getting much better performance afterwards. What kind of, if any, options are available for the ISF?
So far, the most I can gather is a CAI (which I have your blue one en route BTW ), headers, exhaust, aerodynamic add-ons, and some random friend of my friend was telling me I should upgrade the pulleys b/c that would add 15hp to the front and rear.

Thanks, Joe-Z. I look forward to adding the CAI this week, and hopefully the full exhaust system before too long!

 

Tuning is primarily adjusting the ECU to be more aggressive with things like timing, booast, detonation, etc... The problem with the IS line is that the ECU hasn't been cracked in the US domestic market so we don't have access to any of that nor do we have forced induction. A dyno for now will basically just tell you the wheel horse power, and than you can track the bolt on modifications to see how much of a net you gain from them.

 

be careful if you decide to upgrade your pulleys. not only are they usually underdriven (meaning they do less work for the altenator etc) but are also missing the harmonic dampener that will wreak havoc on an engine in the long run.

not worth it imo

 

Good to know! Thanks for the heads up!
