ok so i picked up this nice eg hatch and it ran great. for some odd reason it started hitting a 16psi/5200rpm cut. it would cut throttle and rpms would drop to 0 on tach until peddle was lifted then it would kick rpms back up. im running s300 so i decided to hook laptop up to it. we took down street and came back and now car is acting up. sounds like it has a miss or something was messed up by laptop. any ideas. it sounds rough and smells rich. tried new plugs, etc. really could use someone who lives close to look at it and see. willing to pay. any help would be great. 3047909832

 

If you're willing to pay then take it to a real tuner and stop messing around.

 

im not 100 percent sure its in tune. thats why im asking around

 

sounds like tune combined with wastegate issues and possibly did some damage being that now its missfiring, good luck

 

U might want to do a compression test and look things over mechanically before lining up a tune. Really sounds more mechanical.
