Im getting more tempted to change mine now after knowing the results.

Me too. I would love 4.56s but I think they would be a little ridiculous if I ever drop back down to stock-size tires.

Out of curiosity, who did your swap and what did they charge?

A place called Dannys Transmission in London Ontario the total cost with tax was 2300.00 and well worth every penny in my opioion

ya you know it is we get nailed 13 percent tax on just about everything including labour and there is also the fact that it seems that no matter where the exchange rate is that we have to pay alot more for parts here but like it said it is worth ever penny im getting atleast 4 to 6 mph more now

I take it you meant MPG, not MPH. Did you recalibrate the PCM, for the gear swap? If not, it will appear that you are getting better mileage than you really are.

Yes I meant MPG and yes I did recalibrate the speedo with my diablo

Just an update to the gear swap I downloaded the 87 octane tune into the truck and had the boys from diablo modify it for the gear swap to get my speedo reading correctly. I downloaded that tune into the truck and man does it work great. The speedo in dead nuts on by the gps and the truck will actually sqwauk the tires shifting into second gear something it has never done before So far Im very happy and impressed with the gear swap Will probably be hooking the trailer onto it this weekend to see how it performs towing. Will update after I do
