#287 of 340 Superchips Cortex programmer? by 2007denali Nov 30, 2007 (9:30 am)
Has anyone out there purchased a Superchips Cortex programmer for there vehicle? I called Superchips and they told me it would add 32 horsepower & 35 ft lbs torque to my 2007 GMC Sierra Denali AWD with the 6.2L 403hp/417tq engine.   I'm just wondering if it is worth it. Thanks.

Replying to: dlovesb (Nov 25, 2007 6:56 pm) Hi dlovesb, I'll check out the Autozone guys , there are 2 in my neighborhood. Coupla questions for you regarding the exhaust system....what year is your PU? what engine do you have ? did you notice any performance issues? have you heard the Magnaflow system? Those 2 seem to be the most popular. Someone said they thought Magnaflow sounded better but I haven't heard either one If you have a digital camera, the time and inclination, you could record the sound and send it via email Maybe someone else could do the Magnaflow system And maybe someone could organise a library on the web of exhaust sounds, how cool would that be?

Replying to: tbdomenz (Dec 05, 2007 9:07 am) If you go to the manufacturer's website they usually have .wav files so that you can "experience" their exhaust tone. Some sites like corsa will even have sound files for different vehicles with the corsa exhaust. I think you have a better chance there than having someone record it for you.
#291 of 340 press request by kirstie_h HOST Dec 05, 2007 (5:17 pm)
A reporter seeks consumers who have decided to keep their truck, instead of purchasing a new one, given the economic climate. If you’re a home builder, that would be even more helpful. Please send your daytime contact information to ctalatiedmunds.com no later than Monday, December 10, 2007.

Replying to: tbdomenz (Dec 05, 2007 9:07 am) Hi TBDOMENZ. I have a 1999 siverado z71 4x4 with the series 40 flowmaster.I had the exhaust installed at a muffler and brake( actual name) shop. It starts at the cat and flows into the flowmaster single inlet then splits into two 2 1/2 "pipes from the single outlet that are angled out the back behind tires. The tips are rounded stainless and are over 12" long each. This shop also installs the magnaflow but agreed with the flowmaster as the loudest. I love overpasses and the Boston tunnel! The cost 500.00 installed and garranteed.Performance is improved or at least I think it added pep. You can got to the flowmaster website and hear all the mufflers for yourself. If you want even more power and sound , remove square airfilter box right out of truck. Replace with an airhog square filter that will fit like any other one and zip tie the filter in place. Face the filter down and let the air from the bottom of the truck under the hood blast into it! I clean the filter about every 3 months with the cleaning kit that you only buy once. it gets about as dirty as it would in that big box but with the entire surface of air getting in it!

remove the restrictive screen on the MAF with a dremel and watch the air flow.

Can I tell from a VIN just what size engine was built for a particular model ?? Also, is there any way to determine the difference between a Vortec 5300 and a Vortec 4800 by looking at the 2 engines ? Thanks so much for your help !!   BTW - I just bought a 2005 Silverado Z71
