speaking of this Ive been thinking of doing the MAF mod. and with 133k on my 94 i would like any other ideas on upping performance and life of the truck I have had it since new and not been hard on it at all. need to change o2 sensor and replace exhaust and maybe other things too. I am pretty adept with tools, just dont have a lot of time to research things as my work keeps me busy. But I want to keep my truck and take my family out. just want to keep my truck performing as it should or better. Any ideas or links would be great. thanks.
