your cat eff codes will never complete. And basically all you are doing is telling the ECM to ignore the code when it is thrown. As long as you do not need to pass emissions, there should be no harmful effects.

It holds for all tunes.
The P0420 is a value in the computer. The tunes modify numerous values to increase performance. So this is just something you disable. Vince can do it.
Tell him you want the Cat Delete. Most GM tuners understand that means turn off P0420.

Actually, I was more interested in the additional horsepower! Does that hold true with the Trifecta tune? Would love an additional 25+ at the wheels. Our cars are registered in Florida so we skip the Nevada smog check BS.

I have a 2007 Sky Redline, just purchased the Magnaflow 3.0 in catback, with a pop in K&N filter, with the GM turbo upgrade, does anyone know the horsepower gain with these additions.
I have a question...Miller or to anyone... I have done after market upgrades. Done brakes upgrade to everything. But my question is has anyone got their car tuned? I have had mine tuned a few times. It's holding back pressure. And we can't get it to boost past 24psi. Anyone got advice. Would love it please.

Be carefull with that... NV (CA too) has rules about residents with out of state registrations. :/
NV (northern NV... Reno/Winnemucca) cops gave me all kinds of crap any time they stopped me about my out of state plates. Some crap about once you've lived in the state for 30 days, yadda yadda...
CA has similar rules (that even apply to military folks) and they are so assinine that they TOWED my father in law's car when parked on the street (it was only IN FRONT OF MY HOUSE, lol) for a few days with NV plates. :|
(Basically, we thought it was our pain in the ass neighbor (she always bitches about eyesores, etc). It was actually feedback from other neighborhoods complaining that the sweepers could never do their job. So, the sherrifs went around putting stickers on cars with the tow trucks coming along the next day. My wife never saw the sticker on the front window but she was IN OUR HOUSE when the car was towed! They never knocked or anything! Of course this crap happened when I was deployed. $$$ grabbing crap (had to pay tow fee and storage cause the stupid place closed early)
