Default Resistor module to improve MPG & HP?

What's up all? Just dropped the family mini and purchased 01 black PT (wife used my Ram to trade for an 04 Impala and stuck me the the 98 Olds mini). Never thought I wanted a PT, then I sat in it and adjusted the seat, took a short drive liked. This is cool and the little ones love it. By the way any way to drop the power seat down an inch it's bottom'd out now.

Anyway onto the subject. Just did an in-town micromileage drive and got 18.5 MPG on first tank. Checked into performance chips and was these things on Ebay. Basically sounds like a resistor to change parameters on the air/fuel mix or perhaps changing auto shifting RPM. They say it gives 4-5 MPG more and up to 17 HP increase. What's the deal here? Anyone know anything about these things. Are there actual chips out there for these Cruisers to actually do this? Used to have a GN and the basic performance chip just changed the gearing shifts to hit the gears quicker and adjust turbo boost.

Can't wait to tinker with this Cruiser a bit. Focusing on the exterior/interior first. Going for the total blackout look. Looking through this Forum the transmissions seem a little sketchy, any PM to avoid the problem?

4-5 more mpg! 17 more hp! Snake oil. I wish it was that easy. All the resistor does is advance the timing. Does nothing for faster auto shifts.

This is the only chip I've heard PT owners being happy with.

Mean Green is exactly right on the resistor. Fools the engine into thinking there's colder air coming into the engine and advances the timing which feeds more fuel into the engine. Maybe get a little (2-5hp) out of it but it's doing it all the time, even at idle, so how they claim more MPG is mind boggling.

Figured something was amiss....As they say "If it sounds too good to be true, it is". I'm thinkin' this is going to be a fun family/hobby car. After driving it a bit, I kinda wish I got the 5 speed, seems it would be quite fun with a manual.

Stay out of boost, keep the car properly tuned, keep tires properly inflated and avoiding jack rabbit starts are the only ways you can get the best mpg. There are no magic gizmos. Looking For A Miracle: We Test Automotive 'Fuel Savers' - Popular Mechanics

If I stay out of boost I can increase mpg by 5 mpg. For some strange reason I always get better mpg when my wife is in the car.

I've noticed the RPM idle seems a touch high. Whats the factory setting? This may account for a little MPG problems. Does the 5 speed idle lower maybe accounting for it's better MPG? Just random thoughts.

The idle is around 900 rpms. You get better mpg in a 5 speed because you can shift in the lower rpms while the auto shifts at set higher rpms. Even when you manually shift the autostick it doesn't shift right away and shifts in the higher rpms than were you wanted it to shift.
