I'm looking at some cheap mods to increase the HP in my GTP. Performance chips seem to fit the bill. but are they a scam? im looking at this one, up to 35more HP:
eBay Motors: Pontiac Grand Prix /GTP NITRO Performance Chip/Module (item 280268014340 end time Sep-19-08 19:10:04 PDT)
this one, up to 15 more HP:
eBay Motors: Pontiac Grand AM / Prix Performance Speed Chip / Module (item 300259699031 end time Sep-22-08 21:16:41 PDT)
which would be better? the first one claims more HP

if those wont work, would a more expensive one work?
they claim better fuel economy also. is this true?
i would like your opinions
what exactly do they do?
i am also planning on getting a K&N filter. only $45 for (what i hear) ~5% more HP. are these worth it? any disadvantages?
im trying to increase HP on the cheap, so suggestions would be greatly appreciated.

just get a tuner, chips are a joke in my opinion. from what I understand you can change the orbit of the moon with a tuner.

Save your money. Those things on ebay are pointless and worthless. Save your money and get a HP Tuner or Power Tuner.

ok

what is a tuner? and how much does it cost?

A tuner is a software package that you can use with a laptop (I suppose a desktop too) that hooks into the cars ODB II port and gives you read and write access to the cars computer, thus allowing you to change things such as fueling, timing, shift points, fan turn on temps, etc. Its a double edged sword. It is a wonderful tool that will open up an unbelievable world of fine tuning your engine and transmission but it can also be a disaster in the hands of someone that has no clue as to what they are doing and can easily grenade your engine.

It is a wise piece of advice that if you purchase one you do lots and lots and lots of reading and ask lots and lots and lots of questions before you actually start modifying the computer.

Those e-bay speed chips are just a little resistor that you wire into you IAT and it tricks IAT into thinking it's getting 32 degree air and supposedly commands more timing. Doesn't really work. If you don't want to tune you can buy a programmed pcm for about $100.

link please to the $100 pcm. and this $100 pcm would really make a difference? it would be better than a 30$ chip? what kind of difference would it make? and how would it effect my MPG (help, hurt, or no difference)?

its gonna help u all the way around IMO

INTENSE-Racing.com: INTENSE™ Reprogrammed 3800 Powertrain Control Module (PCM) <<<link for $100 pcm. Overkill is a better option,but at a higher price. From what ive seen & heard its worth it to hold out for the Overkill PCM. Oh, and as for the fuel economy, your foot has the most effect on your MPG's

I hear that these are the best tunes though. Plus if you ever need another tune they will do it for 50 Bucks
