have a stock 2013 ipl 6mt and am not planning any mods. but am wondering what a level 1 tune from z1 would do with 91 octane. the ipl already has some extra tune compared to a non-ipl so am guessing the difference isn't worth the trouble.

 

Without intake & exhaust mods, an aftermarket tune will probably be negligible, particularly on an IPL... which already has a better exhaust and tweak to the factory tune. If you want to keep your IPL stock, but want a noticeable change in the low-end and mid-range, consider swapping in some short rear gears. It will cost you a few grand in parts & labor, but man it is so worth it.

Otherwise, the IPL is a unique and special car. If it's in good shape, you might want to just leave it alone and enjoy the car as is.

 

I just recently updated my RWD Sport model with a tune from Eugene (EAC) so I will let you know my thoughts. I am running the IPL exhaust (off a Nismo Z) with 2.5" custom tubing/mufflers after the resonators, so I am close to your setup.

Since the IPL already runs the Nismo tune to hit the 350chp mark, I'd be hesitant to mess with it personally.

 

thanks guys appreciate it. will leave it as is
