i have a question about this that has probably been covered somewhere on here but i live in a small town in s/w kansas and there are no speed shops in my area.. im pretty new to the whole tuning thing and im wondering if i swap to a 6# pulley is there a tuner i can buy that would have a tune on it to get me by untill im able to get to a speed shop? i just bought the truck a few weeks ago and it came with a (sct) tuner in the glovebox that the original owner used to turn off the egr and rear 02 sensors so there wont be a check engine light.. (egr and cats are removed) any help or advice would be greatly appreciated.
