I'm wondering what is the best chip for the money on my blazer? any suggestions?

 

No 'chip' for your Blazer. You have a Power Control Module (PCM) that must be programmed with either a handheld like a Hypertech or send it to a tuning service like PCMforless.com or wait4meperformance.com

 

so you cant get a performance chip that you just plug in where the existing stock chip is???

 

Get on www.Summitracing.com, enter your vehicle year, make, model, and engine size and they will have aftermarket chips/modules, but be warned that the stage 2 chips do require a 180 thermostat, free flowing exhaust, and 91 octane or greater fuel. Personally, if the motor is stock an i didnt want to spend much in modifications, i would get the stage 1 JET chip and be done.

 

And you are just wasting your money. Chips must be burnt for the exact mods done to the engine, too many variables to burn a one fits all.

All mass produced chips do is up the timing. This in turn makes the engine run hotter and thats why you must also buy a cooler t-stat. Its nothing you can't do yourself in the drive way with a timing light and a parts store cooler t-stat but there are no real gains from it.

 

Don't kid yourself with off-the-shelf "One tune fits all" chips. There's a reason people pay to have their PCM tuned for the mods they have done.

You'll be happy with a tune from either of the companies mentioned, but just say no to Hypertech, Jet Chips, and all other handheld tuners/chips. PCM4less has reasonable pricing too.

 

Would tuning a pcm for a stock vehicle do anything for it? I read on another thread that it could be made to have more power and better gas mileage even without mods. If that were true, why wouldn't they do it from the factory? Just wondering, was thinking about doing a pcm for mine if it would do anything for it

 

You can get a bit more power out of it bone stock but the price you are gonna pay really isn't justifiable on a bone stock engine. Much better off just doing some simple tweaks to the engine the ECM won't mind and run it like that.

 

Like mentioned above the only worthwhile "tune" for your vehicle is a PCM tune from one of the aforementioned companies or buying the tuning software for yourself and learning the art. Even on a stock vehicle you will see some gains, although marginal.
