disclaimer: Im a Super Noob when it comes to tuning
So Im a regular car guy. I do most mechanic work myself but I recently took on a big project(big for me at least). I picked up a 07 escalade with a bad lifter. I was hoping to get away with just a cam and lifter job but that quickly turned into a complete rebuild after further investigation (found tons of metal glitter in the oil). anyways 2 months later and a ton of Ebay/rockauto/amazon parts I got her together again with a few performance parts (stage 2 cam, valve springs, polished valves, shorty heaters, injectors and a bunch of stuff I can't remember). long story short I had worked with a diablo sport tuner a while back when I fixed up a 5.7 hemi I had a while back but I was trying to take it to the next level with a mpv12 tuner (haven't pulled the trigger but its in my cart) but after watching a few vids on youtube its a bit overwhelming. truck runs like shit right now but that's expected after deleting the dod and putting in the new cam. any advise you guys can give me would be greatly appreciated.
