1991 eddie bauer
hi everyone, im a young guy and have very little experience with performance off-roading vehicles. i need some help figuring out what type of performance pcm modifications to do. my suv is a 1991 explorer eddie bauer 4dr 4wd. the modifications that i have done so far are headers, performance cam, bored out cylinders, and 4.11 ring and pinion. my question is: what are my options concerning performance pcm upgrades, meaning re-flash? piggy-back module? chip?...so please if anyone has experience with performance pcm work i could really use some help. thanks
