I am installing a TFS Stage 1 cam with the setup in sig. I am seriously considering sending my lower to TMOSS for porting. I understand the man does quality work. Just wanted to hear some real world experience.
I have a TMOSS ported Cobra/GT40 lower. He did a great job, portmatched to a FEL 1250. You might want to PM him cause if you aren't planning on changing out the heads then if probably won't be any better than the stock Cobra lower with stock heads. Shoot him a PM and ask he's an honest guy from all of my dealings with him.
I didn't even look at your sig at first just hit reply. Sorry bout that.
I would say go ahead and have it ported I think it was a little over a hundred bucks with shipping it has been a while though. When I had mine ported tmoss asked me what I had for heads and I told him them were stock. He said that because I was running the E7s I probably wouldn't see as big of a gain like I would with an aftermarket head cause there would be a restriction at the head/intake flange.
he is a straight up guy and very helpful in all my dealings with him.
