im assuming its a tune that would not touch timing, and whats the point of that, basically not gonna get anything out of it, i looked into it many times. the only thing that could be done is af adjusting and whats that gonna do. not much. so basically you are gonna pay for a tune that is expensive and not get anything out of it. the whole point is to adjust timing for spray and you would be unable to do that because if you retard the timing for spray it is gonna be a slug on motor. maybe a little different with srt-6 but the guys talking about this are n/a crossfires. imo not worth the money at this time without being able to switch between maps and have a nitrous map and na map, on my z i am using a turboxs utec which i can switch between 5 maps, i have a n/a tune, and a 100 shot tune right now, and i just picked up a procharger that will be getting put on over winter and a tune, and i am losing the spray and going with the procharger and meth kit so i will also have a tune for the meth with the procharger on another map. then prolly do another map for high octane, if this could somehow be used with the crossfire gang it would be a big impovement.
