    i have a 2005 1500 silverado with the 5.3 v8 and i was wondering if anyone has put a superchip flashpaq or cortex in their vehicles and what did they notice...if anyone could share about experience with a superchip in the same truck i have (2005 1500 silverado with the 5.3 v8) i would apreciate it.
    Im lookin to find how much horsepower did you actually get, acceleration, fuel economy, and was it worth the $400

    Everyone on here is gonna tell you to save your money and go with a custom tune. From either wait4meperformance or Blackbear. Gonna get alot better results by using their tunes.

    my only problem with custom tunes is that you cant change your tune on the fly... i would like the economy tune for regular use but when hauling heavy loads i would like to have a towing or performance tune....

    my buddy has an 08 2500 silverado with a superchip, he told me that you can set your truck back to stock as one of the settings on the chip.

    how much does a custom tuning cost?

    Superchip help?

    I also have a 05 Z-71. I tried Superchips and Hypertech and both didnt do anything. Tried a Diablo Preditor and after learning how to fine tune it from there website forum its great! You can adjust the normal thiongs like tire,gear etc. but you can also adjust the Long Term Fuel Trims (this really made a big differance) add timing, adjust idle, tranny shift firmnes, tranny shift quickness, tranny shift points and much more. Takes alittle time to learn how to make adjustments but its worth it. It also has a live data section so you can drive and look at what the motor is performing. Every truck is differant so its nice to be able to make your fine tuning adjustments yourself and not have to send your computer back to someone to change a tune. If you live near a shop that can dyno tune your truck than I think thats the way to go other wise try the Diablo.

    cortex superchip

    I put one in my pontiac g8 gt (6.0 liter) and used the cai specific 93 octane tune. I will say it made a HECK of a difference in power and shifting. I don't know about the 5.3 but the 6.0's get similar gains as those with a custom tune.

    thats funny because i was just about to buy a pontiac g8 gt 6.0 liter but at the last minute i bought my silverado instead (cheaper, had 9,000 miles on it, and i love off roading). the g8 gt is a FAST machine...sometimes i wish i went with the g8
