C6-69 rwhp Increase
I was snooping over in C6 Tech and saw evilways' post today. Pretty amazing, those LS engines.
His auto trans went in for a custom grind cam, LG headers (stock exhaust still) and a dyno tune. Net result: increase of 69 rwhp!
Here's part of his post in C6:
"Dyno'd and tuned today
Just got back from Carolina Auto Masters with my 06 C6 A6. Jeff and his crew installed a custom grind cam, LG longtubes with cats,160 stat, and did a tune for me. I was hoping for 400 RWHP and a stealthy feel, here's the results:
Stock dyno run: 337.4 rwhp
After mods dyno run: 406.5 rwhp"

I agree. I remember when the LS1 first replaced the LT1....there were a lot of skeptics (at least in the f-body world where I was back then). It didn't take the aftermarket too long to catch up and pass the LTx engines. My C5 picked up 123 rwhp from heads, cam, headers, underdrive pulley and tuning. That is with a fairly mild cam and conservative tuning. I have been very impressed with how the LS7 has reacted to mild mods and tuning. Can't wait to see what the Corvette engineers come up with for the next iteration of engine.
