Keeps it in v8 mode. Seem to get better highway mileage. Seems to burn a bit of oil still.

Great customer service and fast shipping. The predator added some serious power in addition to my magnaflow exhaust, air intake and throttle body spacer. I only have the programmer on the 87 octane tune and the results are very noticeable. Can't wait to try out the other tunes! I would highly recommend this product and site.

I ran this on setting 2 of 4 because I could use 88 octane. The throttle response and tranny shift was better but it kept shifting down constantly with minimal amount of throttle. I had to put 91 octane in to run setting 3(Tow Mode)but I love how it runs and it isn't constantly shifting down anymore. I have a fast Duramax so this stock rig was painful to get use to being it was so slow but the edge chip changed all that and I now love this Tahoe. I gained a second from 55 mph to 75 mph, going from 6 seconds to 5 seconds.
