I've tried searching, haven't found anything for my situation. First, I don't tow anything other than a couple jet-ski's at the moment, but that could change in the coming years. I also don't have gauges, but should by late January (Isspro). 90% of my driving is city miles. I don't really want to do transmission upgrades. No aftermarket exhaust system will be added. Now, I've been leaning to the EZ, but have heard it's best for towing. What about injectors? DDI or II? This will MORE THAN LIKELY be my only engine upgrade. ANy help would be much appreciated!
