I went to DynoSpeed/Premier Motorsports in Memphis yesterday to dyno tune the Camaro. Forest (Gump for short), did the tune and he did a great job. I was surely expecting higher numbers, but with 99 degree temps and high humidity, I was ok with it. What was impressive is that he was able to fix a 5500 rpm stumble and he got 21 more foot pounds of torque and another 12 HP from my Janetty email tune. More interesting, the Memphis International Raceway opened for the first time yesterday for test and tune...it was awesome. What really tells the temperature/humidity story was the very poor ETs for all of the cars. Examples: my Camaro ran a best of 12.98 worst 13.03 has always run 12.7s, no one in the street tire lanes beat me, including a Viper (13.2), C6 Vette (13.2), Challenger R/T (13.6), 4 other 5th Gen Camaros all LS3s running 13.2 to 13.6 including one supercharged) etc. etc. So, did the tune work, not so impressive on the dyno chart but compared to others at the drag strip, I got a winner...can't wait until cooler weather!
Oh, Forest said VaraRam equipped cars dyno a little lower than realtime power because the Vararam expects speed to give it the Ram Air effect.

I think thats just horrible a stock L99 will dyno around 315hp Dint they come stock with like 400hp? So what they lost like 70hp? I know 01-02 ls1s will pull them numbers and being lighter thats not good for the L99. This kinda makes me mad because when I get my new SS It's gonna be the L99......

Jesus Christ. I'm so tired of these noob posts. What the car actually makes at the wheels (rwhp) is the power that the car has available to it after transmission/driveline inefficiencies are taken into consideration (hence a dyno pull). There is a parasitic loss of power to the transmission, even more in this case because it's an auto, but that doesn't mean that the engine isn't actually producing 400hp.

Had a dyno day at sin city performance last sat. And my 2012 L99 put down 363hp & 360tq on the first pull the coolant temp was 160 on my second pull the temp was right at 190 and the car made 345hp and 359tq and third run temp was at 215 he car made 340hp and 350tq... The pulls were all back to back... All I have done is a cherry bomb extreme catback... Did better than I thought it would!!!

Wow,

My 2010 L99 only did 367HP and 373 TQ with LT's, high flow cats, CAI brand intake, and ADM race scoop on a load bearing dynocomp dyno tune.
