65-75 horsepower at the wheels and 85-95 ft/ lbs. of torque at the wheels depending on the fuel octane and exhaust system used.

We don't have a cost for reflashing. Your VIN is registered in our system and can be reflashed as many times as need be. Dealers might charge labor, we don't control that.

What is the process to retune the car due to a modification pending you had a GAIC tune and wanted to change to say non vtg turbos or wanting to run race fuel and it's not currently supported by their tune?

As I mentioned that GAIC did not provide custom tuning and was met with much resistance, there have been several people also suggesting this.

Do you in fact provide custom tuning support, if so what is that detailed process like?
There are quite a few customers on 6speed who have been setup with loggers for custom tweaking. For people who are asking a for a little more on a specific hardware configuration that we're extracting maximum power from, we will not offer custom options for that specific configuration. That's not to say they could not add additional hardware and receive support, though. This would be something that would allow for more aggressive race modes, etc...

Depending on the modifications made (you mentioned turbocharger changes), the car might need to come in for dyno time. We prefer significant adjustments happen with one of our tuning partners as we can spend weeks at a time if need be making adjustments, versus renting dyno time at a local dyno, which may or may not be setup well for dyno testing Turbo Porsches and hoping we can make something great in 6 dyno pulls (all 3 minutes apart). In cases like that, we want to be sure that we're extremely comfortable with the data that we're receiving. This is partly why you see a lot of new options coming from the likes of Champion Motorsport, AWE Tuning and GMG Racing. We have a well established development relationship with them and this allows the calibrations that we produce to be that much better.

Stage7, longboarder, kenromero, and a few others have custom tuning options with direct logging capability using GIAC loggers.

I don't recall speaking with yllwturbo about custom tuning his car, and certainly wouldn't have said no.

i originally got my upgrade kit from GMG (headers, exhaust, springs, and GIAC tune). i've added a plenum y pipe and fender intakes on my car so i called Allen at GMG to see if they can custom tune my car.
Allen said he called GIAC and they ARE not doing custom tune but if i want i can call them to see if they change their mind.
i called GIAC about bringing my car in for a custom tune. i remembered it was Andrew at GIAC said " they dont do custom tune because they are too busy" i'm not sure if Austin and Andrew are the same person?

ITs GOOD TO KNOW THAT AUSTIN WILL CUSTOM TUNE MY CAR. what do i need to do to set up a date for my custom tune? i should be getting my car back in about a month. THANK YOU AUSTIN

Baseline numbers are higher on the Turbo S. We can reach the same power levels with either model.

Where are you getting the car back from? Feel free to PM me.

Are there any dyno graphs for stage 2 vs stage 2 race programs? Any comparisons.

This is a great question. I am dying to know the answer. When I put race gas and switched to the race gas file from the regular stage 2 pump gas file in Albuquerque my elapsed times in the quarter mile fell by .5 to .7 seconds. I felt a massive massive difference in power when I used top level race gas and the race gas tune file.

Also I am still waiting to see a Dyno graph of the differences between using the stage 2 pump gas or race gas tune file with a high flow catted exhaust vs a catless exhaust.

I really want to know what, if any, the power gain is between using a high flow catted exhaust and a Catless exhaust on GIAC Stage 2 and if there is an effect on heat soak when doing repeated Dyno pulls.

I was thinking the same thing and we have EP. It would be nice for someone to fabricate a testpipe for us.

Austin,
Strange question, but you happen to have a dyno graph of Stage 2 in sport mode(over boost) vs normal mode?

I would expect a Big difference at the lower RPMs

I will go back through our dyno data and see what I can grab to post here for you regarding this, and the non-overboost mode graphs.

Can you PM me who you were in correspondence with? I can follow up with them and see what the hold up might be.

I really am very interested to see the Dyno comparison with the Stage 2 tune between Catless and high flow cats. Tubi street vs Tubi
Race for example
