I have a bone stock c6 ls2 m6. I'm getting ready to order my kit. I have 1 7/8 headers and 3" exhaust on the way. Also will be running an ecs meth kit. With the v3 si head unit will the 3.4 be ok on my stock engine? Trying to get close to 700whp without a cam. What kind of numbers are you guys putting down with the 3.4 pulley?

So Slow

My car although is a 09 model with a LS3 and auto was setup similar to yours before I did a cam swap. Here is the dyno sheet with a 3.4 pulley and a very mild tune. I had just installed a very loose 2800 stall before this.



Here is the dyno sheet after Lethal racing installed one of their night fury shafts ..



I drive the car daily and never had a problem running a 3.4 pulley on the car
with the stock bottom end.
