Where can I find very small gauges,, oil p.s.i. and volts combined OR a power programmer type approach where I can see the same.

Power programmer approach would be better since I could remove my speed limiter?

I am looking for something small not bulky.

Any ideas??

For gauges, you can look for an aeroforce interceptor, or a scangauge 2.

IDK your options for programmer, I use HPTuners

 

It all depends an what you want.
You could get an elm327 from ebay/amazon and use a phone/tablet to display gauges. I've been thinking of doing that myself. Probably the cheapest route -just need elm327, app, and possibly a phone windshield mount.

I've head good thinks of aeroforce gauges, as chibi stated.

I honesty know nothing about tuners, so I can't help you there.
