I have it in my RC. Haven't done any dyno compare between stock and flash. The truck sounds different. A little louder out the exhaust. Probably due to different timing. I think seat of the pants it feels a little stronger. I'm in NC and apparently the gas isn't as advertised at 93 octane. I had to send mine back and have the 91 octane program loaded due to pinging. I'm also going to do the 170 stat and a Magnaflow eventually. That's probably going to be the extent of my mods. I would suggest doing the whole computer. That way you'll have the stock computer for when you have warranty work done. Hope this helped.stick said:I know that the computer flash helps alot in the qc, does it help the rc at all.
would you recommend the flash or the whole computer change? will boomer have this product
