All I can say is wow!! It pulls a lot harder up top, no crap. Just looking at the speedo climb the way it did made me almost cream my pants. Some may think im stupid when im about to say this, but I still have not gotten a custom tune. I will hit up James very soon. As for right now, i am still running the Predator pulley tune and running real rich. The next thing will definitely be tires. Either BFG's or Nittos, what do ya'll suggest? Do the BFG's grip that much better then the nittos, or is it overrated? The cobra is my daily, so just to let you know. Plus i wish i had ran my car when it was pullied to see what i got in the 1/4mile but never had the chance too. What do you estimate my times will be now with the ported blower. Im seeing a lot of low-mid 11's at 120-125, but then again ive seen some people trap 118-119. I hope this blower is worth it when I hook it up to the dyno, im sure Steggy did a good job with the port and cant thank them enough. Wish me luck guys!
