That's nice power! You're going to give those stock 5.0, and Srt-10 challengers a serious run with that.

Nice man must be fun finally!

Im am curious why you didn't swap the 8psi pulley out for a higher psi one if you decided to dyno tune. Didn't you keep the 8 just to be able to run the canned tune?

What is the highest psi pulley you can get from gtm for this s1 kit?

Just came back from Zdayz , running the dragon and his cousins... The car performed well, lots of power. Suspension upgrades are in order...

As far as the pulley... The 84mm pulley came with the kit. As far as I know that's the smallest one GTM offers.... I'm not very versed on the different pulley sizes and boost differences that they provide.. : /
