I am slowly converting over to the "get everything perfect" mentality. it can matter. "good enough" isn't always that.
anyway, my issue was caused mostly by not knowing the correct size of the FIC injectors i got from muhthugga to begin with. it just seems when i switched to the 57 lb injectors my issue was exacerbated even further. I'm not sure how much better it would have been had i a set of injectors that had an accurate data set associated with them.
but, the bottom line is my tune was just scaled, inadvertently. which is fine, i guess. the end result is the same.
purists will balk at this because it isn't "right," but meh. my AFR and trims are all where i want them. drive-ability with my setup is fine. i have no complaints.
