I just received a "chip" off of internet that states i will get up to 35 more horses out of my xlr, it is a resistor that plugs? into the Intake air temperature sensor plug in place of the stock sensor, it supposedly keeps the computer fooled that the air temperature is at a certain prime degree. i can set it back to stock in about 2 minutes if i have to take it in for warranty. anyone have one of these? i got one for my gmc truck as well.

A word of caution; I would guess by "prime degree" it would fool the computer into thinking the intake charge air is cooler than it actually is - i.e., denser air, requiring more fuel and a change in timing. If the air temp, fuel level and timing don't match you run the risk of detonation. Good luck, listen for any adverse pinging or knocking noises on hot days.

Great point Paul.........My V is hot enough, why do we always want more from the vehicle we bought when there are others out there that have more and we don't buy those?
Da!
Wow-

Millions of dollars of R & D by GM and this seems like a good idea to you? Only if the chip manufacturer is taking over your warranty!

yeah you guys are right why risk all that for $7.89 for 35hp. i wont put it in, i just wanted someone elses opinion and to see if anybody else has done it yet. but you know the old saying nothing ventured nothing gained.

ok, curiosity got the best of me, i put the resistor that i bought for my gmc truck in to try it, WOW what a diffence it made, didnt get a check engine light once in my 30 mile test run, everything ran fine, more power off the line, shifts were better, would almost give the xlr a run for the money.

just my 2 cents

No one is saying that you are wrong in adding this to your vehicles...............we are just pointing out the not os obvious, and everyone makes up their own minds.

I put a smaller pulley on my Pontiac Daytona 500 Special addition in 2000 and the extra hp I got burnt up a spark plug, burnt up the three condensors and the spark plug dropped into the chamber. Luckily they didn't know about the the small pulley or I wouldn't have gotten a new engine. Stuff happens.

Although I remain highly skeptical, I must admit that I did go to the website for Surge Performance and it does sound interesting. I'd be very careful nevertheless. There is no simple substitute for a full-blown performance tuning, if that's what you really want, and to get one done at a dyno shop will cost you hundreds, not $7.98.

Also, be aware that the company clearly states on their website that they do not make a chip for use in a supercharged environment, so that rules out trying one of these things on a V.

your right, supercharged and diesel rigs will not work with there product. I did this all for kicks, i knew id only be out $20.00 altogether so what the heck. The truck seems fine, i did install the resistor for the xlr in the xlr and took a trip to town 40 miles round trip, maybe a little more power noticed, more torquey (sp), kept on climbing thru rpms, on my way back from town the check engine light came on, got home, disconnected battery and uninstalled chip(resistor) put everything back to stock, im not screwing with it. like you guys said its not worth it. have a good day!

FWIW: I think you are lucky you listened to Bob and others on this site!!

You MAY THINK the GM Dealers are ignorant when it comes to adding aftermarket stuff on your car BUT I will tell you that the onboard computer does log a whole series of events when things are "touched". So when you go into the dealer with your problem as Bob mentioned and swear that the car hasn't been touched you will be found out real quick. The FIRST THING they do is hookup the diagnostic machine to see what's different.

LUCKY YOU!!!
