I lied, there is questions in this post!

I'm looking to order a PCM tune from wait4me, but I literally know nothing about them..

Is the installation/removal challenging or simple? Would it be worth it to a close to stock 4.3? I have a custom exhaust and air intake, not much more

vielen dank!

Yes the removal and installation is very easy, takes me about 3-4 minutes. Although different year trucks have different pcms so mine might be one of the easier ones to install/remove being a 97. And yes for $75 it is worth it. The pcm tune alone will most likely result in bigger gains than both the intake and exhaust combined.
