So happy you are going to the next level!! I'm jealous!
Can't wait to get a ride in that beast!

Had I not run into you, resulting in hooking up with the WAZOO gang, this would never have happened.

Yun,

As stated, your car is being transformed into a real "Beast" since you were kind enough to give me a ride back years ago when I visited the WAZOO boys. All I can do is envy all of you. Best wishes in the build and can't wait to hear and see all the details. Yes, I have regrets now about rebuilding mine as a 350.

Craig,

U went with Pete's intake and exhaust cams right? What did it dyno?

Sorry, I wish I did. I have SGC Stage I, both intake and exhaust. I did not dyno yet and still need to get off my arse to put headers back on with new xpipe and Dynomax muffflers with my other chip. I'm done with trying to pass emissions. I really wanna know about dyno too.

What's the spec on those cams?

Ok and Pete's are larger on he intake

237/.425" I
221/.425" E

I think the consensus is that the LT-5 doesn't need much help on the exhaust side. In my case the exhaust cams were good for another 18rwhp and 20rwtq peak. However, it really was the overall torque curve that was significantly improved.

Dom,

I was given this by Aaron Scott:

STOCK
Intake is split Dur. @ .050 .214 .229 Lift .390
Exhaust Duration @.050 Dur.214 .214 Lift .390

SGC STAGE I

.430 lift with 230 deg @ .050 (both intake and exhaust)

Craig,

As I posted earlier even the larger cube motors find that the LT5 doesn't need lots of help on the exhaust side. Too big an exhaust and power goes out the exhaust ports. Closing exhaust too late costs compression.

Dom,
Thanks and that is what I remember hearing. When I mentioned to Aaron Scott he told me that a lot of R&D went into those specs for the Stage I, II, and III, but I don't know enough to talk to him about it more. I am curious to see the numbers it will put down one day and surely not going to take out the exhaust cams at this point. The car runs strong, but I don't have anything to judge it by since anything more than stock feels good. I know when I hit the g-spot it sometimes gets me scared and I am happy with how much power it has, but still not tuned right so waiting for that day. If I were in Texas I would just drop it off at Corey's and if I were up north I would drop it off at Marc's or Pete's. In Japan or Hawaii I'm on my own.............

The only tuning choice I have here is this racing shop: http://www.advanceauto.jp/corvette/pcm.html
They used to show the LT5 on here and my friend here has his car dyno tuned by them, but it costs about $900 US.

Here is a crappy translation from google chrome, but you get the idea.

Advance Performance Pack DATA - APP-DATA (Updater)

PCM data tuning of Advance Auto

Including the LS1, LS2, LS6, LS7, I will resetting the engine management various data.
Compare contemplating the difference between driving environment and gasoline with the United States is the country of origin of the Corvette, use conditions, the public, etc., and of using run test in various situations, the chassis dynamometer, the accumulation of data over the long-term It is very popular with the user like after.
Needless of asking the only peak power, it also gives a feeling of power that I did well on in pursuit of feeling in the actual running, and ease of handling.
It is possible setting according to the application of driver-like course.We are tuning shop rather than a mass retailer.
That things instead of using a general-purpose data with little effect, is subjected to a setting directly at the current car did on the highest emphasis on discussion with our customers, to maximize performance is the livelihood of our Advance Auto.
In addition, in the working process, and not in such a way as relying on intuition, and we have been working one by one while looking at the data of the chassis dynamometer.
Of course normal car, even in tuning vehicle change of the intake and exhaust system, engine displacement up, the high cam wearing car, etc., and can be further improved performance by resetting.
When you change, such as after-sales parts and change the lift of the intake system (throttle body and air inter-network system), exhaust system, engine body, the cam, to ensure the achievement of the optimum its performance, APP-DATA is, also, It is a work essential in order to align the status quo of the current car.
