Good evening everyone! after spending just shy of $1000 between two different tuners I've decided at the price I can screw my own shit up! I have zero experience with tuning! But hey I think I can at least do a better job than the other two LOL! I just bought the HP Tuners hardware and it'll be here this Tuesday accordingly to U.P.S. I have been watching Goat Rope Garage on you tube for the past few nights and some others as well. My questions are what are some good books or web pages would be good for me to buy/look at? i don't want hand out or it to be done for me. I just don't want to waste anymore time or money on my truck! What i have is a 89 Toyota pickup with a 2002 4.3 Vortec with a marine intake swap that I have decided to swap out to a 0411 ECM from the the old "black box" ECM. Thank you for your input! Brent
