Where will this setup be bottlenecking? I will be installing stock 243 heads and .040 cometic heads soon (everything ordered) but have a question before I spend 300 on a tune. With the mods in my sig would a throttle body or MAF give any gains? I'm not getting a FAST 90mm manifold because there are plenty of people on here making 460+rwhp through the LS6 and around 400whp the gains are usually minimal besides the thing costing an outragous, to my bank account at least, $1000.
I would like to be around 410 at the wheels on a dynojet without changing out the headers but my last dyno how the car is in sig only dynoed 350/360 on a heartbreaker dynodynamic, I figure that would be 370 on a dynojet? Thanks

I know that this is not what you are asking, but a stall will do way more for your et than a FAST at this point in your build. Likely, it will be a bigger impact than heads. Stick with your stock MAF and tb. If you can find a good ported stock tb, that would help a little.
Do I have first hand knowledge on this?...... Yep.
