I have a 2005 Tacoma with 22,000 miles on it, i also own a '99 Toyota Epic X-22. it seems as though my truck has just enough power to tow it; i'm always at high RPM's or constantly running through the gears though. I was considering buying a few parts such as a CAI and Exhaust to help with towing; however, i have read that you also need a MAF sensor calibrator to really get full power out of the new parts and that just resetting your ECU won't do to much. i have heard from a few people that getting aftermarket parts will end up ruining my truck in the long run. will afetrmarket parts help? am i risking it, towing a boat? can you recommend parts that won't void my warrenty? thanks.
