Does anyone know roughly how much a LS1 with longtube headers, borla exhaust, thunder racing MAF and bellows, and a LS6 intake would make??

340 range if manual, 330 range if auto.

Sounds right but alot depends on the dyno but I have similar mods just a few extra with a A4 and with a sht tune put down 338.something. I'm waiting to go back to see what it'll do with the new tune now that it's leaned out, bumped timing, and he did a few other tweaks.

Yup, I'd say Y2K is correct. I put down 330rwhp/342rwtq with LT's, ORY, exhaust and a lid on a Mustang Dyno. I already have the LS6 intake being an 02 and I lost a little hp b/c I have an aftermarket rear-end.

Not only will it depend on the DYNO, but how well your tuner is. Important thing is that the car runs great and your A/F ratio is where it needs to be.
