    i have had my car about a week now since after my 1g swap, did 500 miles of break in, then i tested it out on the freeway. when i am driving on the freeway, at around 65, when i trie to accelerate in 5th, when it gets above around 5 pounds of boost, the car seems to run really rough. my CEL is on as well, random misfire and bad knock sensor. if anyone would car to share some insight on what is going on with my car, it is pissing me off cause it seems a whole lot slower and doesn't run very smoothly at high boost. i figure it needs to be tuned, and if that is the case, which would be better, DSMLink or apexi SAFC with datalogger?

    no one can help?, it also feels rough accelerating in all the gears until it gets to about 3k rpm, then CEL just went off ealier, but i still want to find out if it just needs to be tuned with a fuel controller or if there is something else wrong with it.
