Well, i just went to the track for the first time last night. Had a best of a 8.935 (1/8 mile). It wasa very hot and humid so that might have something to do with it. But, with my mods (in sig) should i get, or even need, a retune. My car has never been dynoed or tuned so i just need some advice on whether it would help or not? Thanks in advance for anyone that decides to chime in and give me an idea.

 

ANY car will benefit greatly from a tune. Your mods aren't necessarily changes that the PCM can't correct for somewhat, but you could be looking at some big gains with a good tune!
