So it turns out, that my service engine soon light is because of the jlt cai I have added along with lt's, and x pipe and th flowmasters. I talked to the guy at the shop and turns out im running lean and I need a tune. I know this isn't good for the engine to run it long like this, and this is my dd. So I have made an appt for a dyno tune. So some time tuesday I will be posting up my numbers for an 04 GT with jlt,bbk lt's, bbk x-pipe and flowmasters. Im not expecting anything impressive, so I wont be getting my hopes up. lol.
