Wouldn't that make the car run too rich or lean depending on where the boost is set in reference to the tuning of the car? Why change it once the car is tuned?

they can have multiple tunes which can just be downloaded to run high/differant boost levels.

I am not a pro tuner and I may not use the right terminology but if you use a different OS that allows for boost, it can be tuned for multiple boost pressures.
So if you change your boost at anytime the PCM along with the New OS will allot the correct fuel, air, and timing for the boost applied.
Someone please add or correct me if I'm wrong.
Hope this helps TNT and BIGBLUE

You can tune with speed density for different boost levels but you can also tune normally and be pretty close if you are not going crazy with boost changes.
Speed density is not the norm in turbo cars from what I have seen. Sure the big hp guys usually run it.
I bought hp tuners to give me the option to run SD. I had tunercat /jet also already for tuning my 96z and it might have worked on the twins but thought hp tuners was better. Still actually a bit disappointed in tuners. It has good forum support and complany support but its so generic it really has not implemented features that turbo guys want and need. Now maybe the ls1 ecu can't do them. The features I really wanted to see are two step launch or stutterbox as its called, anitlag, no lift to shift for stick cars to keep the turbos spooled and mabye some nitrous controls like built in window switch type of thing.
The only way to get this stuff might standalone not sure. At least can log afr with hptuners and would think obviously boost with SD option and you can tune in real time with the expaned maf or SD options. That is handy thing also.
Anyway sure I can make hptuners work for me. Good enough. Not building a track car anyway just a fun street machine.

Both EFILive and HPTuners offer 2 and 3 bar tuning options. Check out the PCM tuning forum for LOTS of details and examples. Simply put, the factory PCM's allow the ability, through custom OS changes from both of these packages, to be fully boost-capable in either speed density or MAF modes. You're going to max out the MAF quickly anyway, so to me is simply makes sense to put it in the bin and tune the car speed density from the beginning. In fact, NOW would be a good time to start your SD tune, and get the drivability at <= 1bar nailed down. Once you install the kit on the car, you're just that much closer, and can concentrate almost purely on 1+ bar tuning.
With the car fully and properly tuned for a certain fuel, you can run a boost controller and set it to (nearly) any boost your heart desires. If you change fuels though, you're changing the rules somewhat. You would need to consider the new variables and set up your tune accordingly.

I know guys like me aren't your main target here, but I was hoping you might be able to test fit one or do some measurements. Don't want to buy the kit and have to modify everything

I can hardly wait for the kit to come out.

Could you guys leave the fins of the intercooler bare if requested?

All the GTO guys got their APS kits within 3-5 business days from leaving Australia. Just saying this because I know I was starting to get a bit worried I'd have to deal with the same crap as the other guys were and wanted to let you know it isn't a concern .
