Well, I think Im doing everything in reverse order of most people. I have a 11.6:1 comp. 382 from speed inc. 415hp. The only bolt ons I have are headers, borla, and a lid. I'm running the stock intake, TB, maf, and pulleys. How much hp am I sacrificing with these stock parts. Also I had my engine tuned by Ed Wright, shortly after my O2 sensors fried and my MAF wont read anything but 4.6 g/s, would his tuning be the cause and what MAF should I invest in.

I think you could pick up another 25-30 rwhp by adding a 58mm TB, pulleys, and porting your intake. I would keep the stock MAF though...don't mess with it IMO

if you have a ls1 intake you could be loosing a lot, upgrade to a ls6, asap. the others can pick you up another 15rwhp+, but the intake is a must imo.
