FRS with Supercharger
 

I have a deposit on one with an HKS supercharger. I'll see the car tomorrow but don't know what to look for regarding how it was set up and what if anything was done to the tuning. Can anyone give some advice?

Maybe read the HKS supercharger threads in the FI section from beginning to end?

Sure. Here's some free advice. Stop making bullshit threads asking about easily searchable matters when we have an entire subforum dedicated to this. HKS even replied to your last one.

Used car dealership right? If so ask what their warranty covers, for how long, etc.
and what shop installed it.
To me it sounds like your buying someone's else's headache. Make sure to look the car over and get a good test drive. Good luck.

I would never buy a car that already has aftermarket FI. There's no way to tell what you're getting into, unless you personally know the seller and the car.

If my car is going to blow up, I want it to be MY fault. Not the result of someone else's shoddy work.

This ^^^^^ All day this!
