So I bought this car in December and the first video is how the car sounded on 93 and meth Injection. You can hear it was really choppy, the second video is how the car sounds after the second owner installed a fore tripple pump system, 1700cc injectors and e85 tune. Would the choppyness being gone be due to the tune? I noticed this car is super fat on the bottom end. Idles around 11.4 afr. I'm having it retuned in may by a shop I trust. It makes around 850-900rwhp I'm told on 18psi with twins. What do you guys think?
