Did you ever find a 180 thermostat. If so where and what kind?
Thanks

i had a K&N intake, Gibson Exhaust and a Jet Stage 2 on my old 05 rubi.
the chip did make a difference, better throttle responce, and HB/TQ

Assuming you do all this, what kind of power gains are we talking about? Round numbers, are you looking at 10+-hp? 50+-hp?

Thanks-

Even with all these add ons you are unlikely to add more than 10hp. Also, keep in mind that all the gains will come in the upper reaches of the RPM band - like over 4000rpm. Also, without installing headers and a performance catalytic converter your "free flow" exhaust isn't doing much other than making noise.

Do you need the Jet Stage I Chip with the Stage II? Can you jump over I and go straight for II?

Rich-twu

You can only use one or the other.

from what i recall... and this may be internet b.s., but the 180 degree thermostat is to prevent detonation due to internal combustion temps. the stage1 is reported to have a noticeable gain in off-idle response and power. the stage2 is supposed to add to this. part of it's change is the fuel and ignition mapping. to prevent detonation, they suggest you use premium fuel and install the thermostat.

With the different chips now available for the JK, is the JET chip as good as the others? I have been looking at several options. Thanks.

The Jet Chip is less money than a programmer. It also doesn't do all the things many programmers can do - such as adjust your speedo for different tire sizes and gear ratios or read trouble codes. I've had plenty of negative feedback about Jet chips, but almost all positive feedback from Hypertech programmers. I would stick with a programmer if you can afford it.
