when i dynoed my car about a month ago, it only mad 275hp and 312tq. it was running extremly rich in the 11's most of the time and into the low 10's at one point during all 3 pulls. i have since had the pcm tuned, and also found out i had 2 injectors that were leaking and that the opti was on the way out. ill be getting my car back tomorrow(hopfully) with new plugs, new opti, and all new injectors. should i see/feel a noticble difference in the power? i was hoping for 290+ with the mods in the sig.

 

anyone

 

yes.

 

You should be a little over 290 as long as your car is now running right.
