Anyone know anything about a speed chip?

Saw this on e-bay, http://cgi.ebay.com/ebaymotors/20HP-POWER-SPEED-CHIP-HUMMER-H2-OR-H3_W0QQitemZ120113762301QQihZ002QQcategoryZ33598QQrdZ1QQcmdZViewItem
 
and was wondering if anyone knew anything about it, or if anyone has put some sort of speed chip in their H3???

SORRY,,, my bad.... I just did the search and found out it isn't good.   Writing before I think again.... Sorry.....

U are better off going to www.pcmforless.com and getting the reprogram of your PCM. It is v ery easy, and
 the results definitely noticable.

Don't do it.  It's just a stupid little resistor you can buy at Radio Shack that gives the computer false air flow readings to pump out more power.  In the long-run it will cause damage to your air flow sensor and cause excessive carbon build up in your engine. 

I don't know anything about speed chips, but I know someone who could tell you about fuel magnets.

OMG....RutDogg..thats some funny chit

  So the re-program from is www.pcmforless.com option will NOT hurt the engine at all?  I could sure use more power going through the higher mountain passes here.

Actually the engine runs better than stock..There is about 50 of us here that has had the tune...So quite screwing around and drop a dime on Kelly at PCMforless and geter done.

I just sent mine out last week to Kelly and should have it back soon. I have heard all good stuff about PCMforless. It's easy to take out and replace. I can't wait!
 

Update....
PCMforless received my PCM yesterday afternoon and Kelly just informed me that today its on the way back to me. 1/2 day turn around! Not bad! Top Notch!
I'll see it soon and we'll see how well it works.

So how much of an increase in HP, pick-up, etc. have you all seen?  Does it help those of us who have the 35's on our Hummers to compensate for the extra weight?

Thanks,

David

I can't say actually what the HP increase is..but I can say, as well as everyone else who has had it done, that there is a noticable increase in pickup and power throughout the throttle range...Couple that with a CAI and a Cat-back exhaust..I guesstimate that I have about 35 to 40 HP gain now.
