Jason when you say calibrates for the intake, this isnt a performance tune and im guessing no added timing either, please correct me if im wrong. The reason im asking is because im trying to figure out what causes the weird torque dip and how did the cold air intake get rid of it, pretty weird.
Edit: there is about a 50 lb-ft torque increase at about 4250 rpms.
The baseline has the torque dip because it's hitting the max allowed power and closing the throttle body. We tune that out and it's gone.
I agree, once the warranty is gone. Most of us won't be able to use the power that we have on the street and it could be a very expensive mod if something unrelated lets go and we still lose our warranty because of it.
Today we A-B tested the Halltech air intake system for the C7 Z06. The system performed incredibly well. So well that it's definitely going to need tuning and cannot be simply bolted onto a stock car.
Baseline with factory calibration - 558hp/568tq
Added the Halltech system with no tune - 585hp/596tq
-This leaned the AFR out to 13.5:1 and it was rattling (knocking) like crazy. The torque was so high because of the AFR and there was a lot of timing to start, but once it started rattling around 4200RPM you can see where the torque dropped.
Calibrated for the intake system - 594hp/575tq
That would go great with an e85 flash, and wing/weight savings!
I have our folks laying up another one with my changes that should bring parity to the factory air fuel ratios
Jim, why would you go back to the stock pig rich A/F.....can't you find a happy medium and get this from 13.5:1 to ~12.5:1 rather than down to the high 11's?
Yes, Phil works for us. We personally go back 15 years so I've known him before I even worked for Katech. Occasionally he breaks away from me long enough to go down to RPM. Sometimes I make him stop by Joliet, IL first.
Awesome to know! He has tuned a couple of my cars, one (2005 Orange C6 with LG G5X3 cam) that I had 5 people tune and Phil was the only one to get it right! Phil is THE MAN!
I look forward to getting the Halltech intake and eventually having Phil tune my beast and unleash all of its power!
Definitely not disappointed in the numbers of the intake and having such an awesome intake you have to slow the flow down is incredible. Using a lower flow filter is an awesome solution if that indeed fixes the issue. That way those of us that decide to tune later can just buy the better flowing filter to get the max out of the intake! Win-Win!

Phil is the best late model GM calibrator in the world in my opinion. That's why he works for us.
These are great results from such a straightforward change. I, like most others, want the increases without voiding the warranty.
Some tuners claim their changes will not void the warranty on corvettes. They even give specific examples of how they preserve calibration files, check-sums and other data that GM corporate techs can check when determining if an aftermarket tune has been flashed.
Many of us would really like to know if it is possible to re-tune a Z06 and not have it detected by GM in the event of a warranty claim. I do not mean leaving the modified tune in place, but restoring the original factory tune from the saved tuner file.

So you would like to know how to commit warranty fraud?
We will have our Synthetic filters next week. Today we'll have the upgraded intake, but it goes out to Texas Speed.
We'll get the new system on our Z06, and one to Katech for testing. The filter may be all that is necessary. We have 180 of the high flow filters in stock, so we'll likely have both filters available, assuming the Synthetic filter is the solution. I know a shorter Syn filter put the Stinger CKN (Stingray system) into the minus LTFTs, so a slightly longer version should get us where we want to be.
For any of our beta testers that do not have dyno capability, we'll wait for the new setup and testing before shipping your intake.

Phil tuned our ULZ700, so that should tell you everything. I have over 12 years tuning experience, but proper tuning has to be done dynamically on the dyno, and on the street. Phil is the best tuner around.
