Next Step? Seeking more HP
About a year ago I purchased my 2006 M6 Z51, the previous owner had installed a LS3 top end along with mild comp cam and stroker kit (413 ci) with supporting mods (10.9 compression) and car put down around 480 to the wheels when I got it.
I was looking for more power but was hesitant to go FI due the build being fairly high compression. I decided to go ahead with an ECS 1500 kit along with DeWitts Radiator, Mantic 9000, and headers. That resulted in roughly 650 rwhp, but I was running out of fuel up top (w/BAP only).
I then added an Alky Control Meth Kit (single nozzle) and ECS stage 1 fuel system which resulted in 750/680 to the wheels. I have become used to the current power level and am looking for the next 50+ hp. Any suggestions on what would be the most cost- effective way to add more power? Also would I be pushing it too far due to the fact that the original build was set up for NA (10.9 compression)? Any info will be appreciated.

I would do a fuel system and smaller pulley. E85 and larger injectors if you can get E85. What is your current pulley size and boost level? Even if you can't get E85 I would pulley down and do a dual nozzle meth setup with whatever ECS recommends for that power level.

It is the stock size pulley that came with the ECS kit (3.25" I think). I am currently seeing about 12 psi max. I do have the ECS stage one fuel system- I think I can order the extra parts to upgrade to the Stage 2. I am trying to stay away from E85. Will it be safe running a smaller pulley than the 3.25"? I am fairly high compression (10.9:1) and have read that most cars built for high boost are usually running lower compression.

Don't need to swap pulley, just pull the restictor plate and add more meth.

12 psi sounds like the plate is already pulled. Dual nozzle meth for sure. Is your cam tailored for a centri blower? You could do a custom cam that is bit more aggressive since you have a stroker.

If the pulley isn't pulled. Single nozzle should be good for 800rwhp, may not need a second yet.
I would call ECS and just see what you need to get another 50.
