I think Drew is talking about the blue curve as 'low boost' there TJ. That curve was put together on about 10 tunes all by 'seat of the pants dyno' and logging with HPTuners. Our second or third pass was the wavyest even up in the high RPMs but we attribute it to wheels not be balanced. The dyno operator, who we know very well, said he sees it a lot when tires have not been balanced, hence us. I think once we started making the power we did the car really drove through the bounciness it was experienceing. I also think the straps where cinched a little tighter after the 3rd or 4th pull.
BTW the downpipe is 3.5"...

I saw a local guy boost his stock ls2 gto to 15psi. I think he made like 675rwhp. Yours is making some kick *** power. Oh yea, the one i saw was like 8 months ago and is still going strong. Those stock ls2 engines are fairly tough. NICE NUMBERS!

Dave has been beating it up good. He has been driving it every day here in Michigan, rain, sleet and a few clear days too. We load up in it, 3-4 of us and make parts runs and what not. He takes the family shopping, you know just a good street car. The ET street radials seem to do ok in everything, just have to be careful on the go pedal.
He has been running 110 with meth. and why not for only 4.50 a gallon, almost seems like a steal for good fuel.
Next spring Dave wants to change it to a pump gas car and hit it really hard with the meth. We just have to set it up to shut the car down if the meth does not work. The ol' stock LS2 will be looking to grenade if it sees the slightest bit of knock.

Well it was 27 degrees today. Dave was driving around and giving rides like usual. The dyno was at a 90-110 degree IAT because of the non moving air. So with the meth rollin down the road IAT's were in the 20 degree area. Bringing ignition timing from 14 degrees (735whp) to 19-20 degress. I imagine he is making close or above 800whp with the current tune in this weather.
