Check this link. It's says it's a MAP sensopr adjuster. this page has some cool stuff on it.

Yes. When you first turn the key on, the ECM takes a reading of atmospheric pressure so it knows where full load is. I think this thing tricks the ECM into thinking that there is a different atmospheric pressure reading when you first turn the key on. Make sense?

 

Cool stuff?.
Your map adjuster is two resistors. Wired up as a voltage divider. Try a 1K, and either a 4.7K, and 10K. Very crude way to do things.

You can make a TBI spacer from hard wood, painted with model airplane paint for $10, and save $76. I've been run a wood one for 5yrs now, with no problems. Painted stealth black, at no extra cost..

Just think of what you just saved....

For the $250 for one of his custom chips, you could be burning your own.

Lots of this stuff, is like the turbulator, or whatever it's current name is. Find a car that runs lean, add something to restrict the air flow, and it can run better, and then you can make a 15 HP claim. Or rechip it a little richer and gain 20.

 

Good points Grumpy!!! I just thought the MAP sensor adjuster was funny stuff. I totally agree with you abotu the Do-it-all(that you can)-yourself theory. and nothing can replace chipping.

No kidding. Why buy one of those injector spacers when you can glue to of the regular gaskets together with RTV and use that. If you do that it's 1/4" tall just like the spacer but it didn't cost $40!!

 

Funny stuff. Check this ebay item, lol

Look at how many people believe this guy.
Maybe they should invest some TIME into an adjustable fuel pressure regulator.

 

Fools Money, yada yada
If your calibration is off (lean) then it will cetainly work. Trouble is ever GM cal I've seen is rich (at WOT).

If your really contemplate it, it can't work any better in cruise since the ecm is maintaining a 14.7:1 average. He just happened to have some gas that varied the results (ie was running with the K/S active).

I just love how folks can tell 1/2 the *facts* and get away with it.

Notice some of the stuff claiming NASA used the product has stopped?. NASA buys one of everything for evaluation, so yes they used all the snake oils, Once or Twice!.

Prom burning content.
I'd like to see any product do better then a chip I could do for the same vehicle <g>
