GIAC Stage 2 is here. Now Available at your local GIAC dealer.

Would there be any issues with a catted DP with catless exhaust set up? I know another poster said about frying your cats at the mid pipe area, but what about keeping your cats at your DPs for emissions purposes? Thanks!

The final report will show everything you need to know about the flash and the transmission type but when GIAC reads the computer, they cannot tell if the car is manual or auto. The dealer needs to specify this information to them.

Getting my car flashed right now- similar issue, GIAC had to write a file for my MT, they only had the AT file. Of course, i'm only getting stage 1. I'll have to ask for a report when it's done.

I remember Austin@GIAC saying that catted DPs (with high-flow cats, not stock) are fine.

Yes, the red line here has AR catted DPs, the blue line has Macht Schnell catless with HFCs in the secondary cat location.

Looks like the catted pipes are stronger low end...

The dyno computer began sampling at 2500 RPMs. It looks to me like that car simply tipped in a bit earlier allowing torque to ramp up a bit harder in that range. That said, the curves are close enough to be within a standard deviation of one another.

What is the required octane to use Stage 2 Race ? Is Sunoco 109RON (104AKI) sufficient ?

kanecvl · 12-24-2010, 01:06 PM

109 is sufficient

That is 109 EU-spec. You mean 104 US-spec is sufficient ?
