There is a lot of cost difference PS1 to PS2.
Not sure if your car is a manual or not.
At 82k FBO RWD my clutch started slipping before I even bought the PS2.

Price difference $1600
New clutch and flywheel $800-900+
Needs a custom tune $300-400+
New LPFP $300-400+

Right off you're spending $3,000 more.
Then you get into tires and suspension parts.

The PS1 is a great option to keep the torque high in the lower RPM range and while a proper tune would be able to maximize its potential you can run it with just a Stage 2 flash or JB4.

Self install budget $2k vs $5k
