Hello all!
I decided to post this in the general Chevy forum so I might get some more traffic, and because the question is fairly general. I recentally purchased an '05 Tahoe, 5.3L. I am interested in buying a chip upgrade, to boost performance and also mpgs... I am unsure where to even start... What is a good chip that will give me the best results for my $$? I have done some looking, but I dont know if I really need an Evolution CTS, or will I get comparable results with a less expensive option? Thanks for the help, I look forward to hanging out on this forum!

try this product http://diablosportpower.com/diablosportpredator.html /or and here http://www.diablosport.com/index.php?module=htmlpages&func=display&pid=3

many find better power . as far as increasing MPG this is not going to happen. your vehicle if properly maintained will get the max. MPG.

more power/performance means lower MPG.

this costs about 300.oo. I believe you can pull ABS codes as well as others with it . nice features for the money. excellant forum as well.

Hayseed, I would ask responders to provide evidence for their claims. I have found on these forums that a lot of people simply make statements of opinion that something will or will not work as if they are fact without offering evidence. When pressed you might find that they are unable to do so. Even a simple, "I've tried it," or, "I have seen the report of a clinical study that stated...," is beyond some responders.

I would replace the plugs ac irridium. check plug wire resistance replace if necessary. replace air filter or clean K&N filter. clean MAF with crc MAF cleaner, and clean the throttle body and IAC with throttle body cleaner. make sure you have no exhaust leaks. then calculate your MPG. do this 3X and get the ave amount. now you have a base line.

add the equipment or the additives with all the claims of higher gas MPG.

continuing to calculate your MPG. then see if all the added cost was worth it. I'LL be here waiting for the details on your results.
