Is the procal worth the money just for the speedo and the tpms?

 

A speeding ticket will cost you more than the procal

 

That was my exact thinking! I also figure it saved me $50 by not having to transfer my TPMS to the new tires/wheels. Who knows if it helped me sell the original tires/wheels since they still have TPMS.

BTW I confirmed with my GPS that my speedometer is dead on. It could not be easier to use.

 

I also like the new shift points (automatic transmission). It shifts back like it did when I had stock tires. Much better to drive at 2000 rpms @ 75mph instead of 3000rpms. Also saw my MPG go up 2 from 13/14 to 15/16.

 

Depends on the tire size difference (29 to 33, yes. 32-33, not so much), and whether the dash light annoys you.


From just a price vs overall functionality viewpoint, hard to beat this little gem.

 

Getting the computer getting the tranny back to the correct shift points is way more worth that the cost of the Procal. It's like adding power back to the engine. Absolute necessity on the 3.8L engine.
