How hard is it to learn with the Tweecer R/T

I did a few searches on tuning with the tweecer and it all looks like some code or foreign language to me. My cars been running like ass lately and Razors Edge hasnt been coming through for me. Is this one of those things where once you try its easy? Like the supercharger/headgasket install and everything, that was scary before I started but now that I tried I could probably do it in half a day.

Ive been to Razors Edge 5 times now and my car still runs like ass. After the 1rst time I went there I blew a headgasket. Now im leaking coolant again but im not sure if its a HG yet or not, I need to get a leakdown tester. My A/f isnt to great and my power curve is like a heart rate moniter after runnign a marathon. Ive asked them 3 times last week to fax my my last dyno sheets but they havent yet. Last time I went I was there for 7 hours and we only got like 4 runs in. My car stalls after everytime I get on it and at stoplights sometime and my idle is crazy. I was going to go to Thunder but I figured if I can do it myself, it will save money for later mods.
