Not to hi-jack your thread or anything, but what would the gains be on a FI car? Let's say LQ9, if any gain...? *newb*

I gained 25/20 at the wheels with my head swap. But I think the heads are too much for my cam. GT2-3 and GMPP CNC LS6 heads(65cc).

I'm planning on going to a different cam that is better for those heads

My heads were done at the same time I added the underdrive pully and Meziere Electric water pump. The 3 added 70 rwhp and 50+ rwtq. My heads are in my sig.
Cam only I was at 403 rwhp and 380 rwtq. I will be updating my numbers after I spend some time at the shop with a local tuner to finalize my tune. I had to get back to Michigan from LG in Texas and we needed to cut a few corners so I didn't get in trouble at work. Wish me luck, looking for a few more ponies and better drivability.
