I'm getting a used Lightning one from the local shop that's going to tune my truck. I changed my plugs a couple weeks ago and now I have a misfire. I have a new set of plugs on the way, and after I get this misfire issue sorted out, I'm going for the pulley and retune.

how are you getting the 10, im at 7 now WOT and want to get to 10 like you?

I see about 8 1/2 in the winter and just over 8 during the summer. I have the +2 lb pulley from Troyer. However, I'm about to pulley up to 10 psi and get it tuned locally. These Roush blowers are rated at 1.8L and there are Whipple/Saleen guys that have run 12 psi on their 2.3L blower for years. The roots style Roush blower will generate a little more heat but shouldn't be more than a 2.3L blower at 12 psi.

To answer your question, 8+ now and 10 in the near future.

hey man, how much boost are you running now?
