I have an Intense pcm and don't really like it. With the mods I have now I shouldn't be far off in a tune, but my LTFT's are -10's on average and I'm getting knock up to 8* reading from my aeroforce. Thats with 3.4" pulley, headers and other basic mods. I already bought a powertuner and will probably throw a DHP .bin on there or start from stock for a tune. Even without the headers the tune was off and was supposed to be setup for the mods I had at that time, i was getting a lot of knock.
A local guy got an Overkill pcm a while ago and loved it. He said the tunes were dead on every time and he was running 12's in his car at that time so I was impressed.
Part of the problem is that your getting the pcm from canada, I bought some fuel rails off of a guy up in canada, he shipped out on the 6th and I didn't get them until the 22nd.
