Only 311 HP was your baseline?? That seems kind of low, but I know dynos vary all over the place.

Andy said that was pretty much the average he was seeing for the L99. Seemed pretty low to me too.

Completely stock, with tune.

The salesman filled it with 87 octane... I ran it out, and filled with 93 octane and then drove for a few days like that. Power actually felt pretty good. I then disconnected the batt, hoping for a little more, immediately noticed a power loss. Check out the a/f ratio.... A little tweaking of the a/f and timing seemed to do the trick. My uncorrected was 345 hp with some cool, dry air here. Going to the track tonight.

It was a So Cal dyno day yesterday. Thanks to Shawn for letting us invade the place.

Bone stock, started doing 6K shifts after 500 miles. Dyno-ed at 1,000 miles. Time for some bolts on for Christmas

Post Ronnies Black SS

Guys,
I had my SS tuned after I installed an MTI cold air intake and American Racing Headers with 3" exhaust plus LMP Mufflers and Dyno numbers were 367.02 rwhp and 386.08 torque. This was with less than 1500 miles on the odometer.

FWIW
I had Kooks LT headers and Highflow cats installed. I already had Solo MachX and CAI inc intake.

Base line pull was 303hp and 350 tq corrected stingy dyno. I was not concerned with the numbers but I was interested in the Delta (difference from base to final).

After headers and a tune, final numbers were 367 (64 hp gain) and 402 Tq (52 tq Gain).

The transmission tune with Torque Management turned off is amazing, shifts like it should have from the factory. Does not have that lag between gears.

The above is my experience, Tuner was very impressed with the combo of parts. He did not expect these number as stated earlier his dyno is stingy.

Dyno Pull

Here is mine. Can anybody explain this to me. It is way down from what I have seen from others. Plus, it is a very rough pull and not smooth like the others.

It looks like your AFR is 15. That is too lean from everything that I have read, except at very low speeds where you are not making much hp.

That AFR line is so steady, I don't think it's a real measurement.

You need to do the fuse pull mod.

It isn't it was like that when they first hooked it up. They never stuck a wand in the tail pipe.

So no AFR was checked.

If I told you I did it and let it sit for 24hrs. would you believe me?
Well I did. I have only put 93 in it since I got the car. Read the fuse pull thread and tried it. No change.

Anybody with any other ideas, I am beginning to wonder if I don't have something else going on?

Should I do the fuse pull again? I won't be driving the car for the next 4 days cause I go back on duty. So It will sit for 4 days. Whatcha think?

Expected a little better with the Superchips program on there.

I am pretty surprised by the numbers that you are all posting. (Is this typical for the Corvette (10-20%) HP drop?) Very interesting...I never would have figured that much from the L99 Camaro!
