So I got the Xcalibrtor and I went with a stock tune which I assume is what is already pre-loaded on it. I did not mess with the spark, fuel, blah blah blah and anyway has anyone had a problem with the SCT? My car seems to bog down when ever it feels like it, my rpms don't shoot up as rapid when I go WOT. It also feels like I have lost so much power. I feel like a honda because I lost all my low-end power.... I'm having 2000 Cougar flashbacks[wrenchin] ... oh and the check engine light is on giving me transaxle codes..... Has anyone had the same experiences?? or similar? any help is appreciated, thanks
