you have a tuner? with a ic and pulley drop i hope you got headers as well. a tune would sure wake it up even more.

I got a custom PCM done by Intense racing, but I don't have an actual tuner. I only dropped to a 3.5 pulley, so I think that will do fine for now. I know every engine is different but I really don't think their tune would be that outside the ballpark.

Either way, I plan on dropping to a 3.2 pulley, getting headers, larger injectors, and with that an actual dyno tune, or HP tuner next. So if I don't like the way it runs with this computer I'll just do that sooner than planned.
