just wondering how much power can be gained by JUST an intake and exhaust modification, with NO software upgrade.

Did anyone test this setup with just and intake and exhaust?

 

not very much...maybe about 20hp total and hardly noticeable. What you will notice is much improved sound.

 

Edit

 

+1 agreed. The tune will bring out the full potential of the bolt ons.

 

i did intake and exhaust and just love it!

 

I assume you didn't do the ECU tune. Glad to hear you like it, that's what I plan on doing until the CPO runs out. Unless my patience runs out first.

 

yup it is great, stirs the senses...AP intake, Tubi exhaust, perfect for me, maybe when warranty is over do a tune

 

I would wait until your warranty is done, 30-40hp more ain't worth the warranty being toast.

Not 45,000$, crate price for a new engine.
The dealer's 'ok' with it means sh$t to PCNA, there is no way PCNA is going to look the other way with a significant engine claim just because of the stealer's word, the dealer has zero input into those decisions. With mods like ECU flashes you are taking your own risk, to imply otherwise is simply not true.
Granted, the motor (997.1tt) is bulletproof, but nothing is free. More HP=more stress on mechanical parts.

Interesting...never thought of it that way

 

You're grasping at straws, Mike. Anybody who wants to mod the ECU should be well aware of the risks, it's not the same as an exhaust. Modifying the engines operating parameters by altering the on board computer is a whole different deal to any manufacturer.
I did it, but I was fully aware of the risks. I'm not saying don't 'mod' your car, just be careful before you cross the ECU line into no-mans warranty land. When they void your warranty for something like that, the entire warranty is done, as it clearly states in the owners manual, happened to a good friend of mine with a gt3 last yr.
I'm just sayin'.....

 

What were your friend's circumstances? Were the warranty claims unrelated to an ECU flash?
PCNA can and probably would try to void the entire warranty, even if failure of a component/system was unrelated to the modification. Legally, of course, they can't do this as I understand it (Magnuson-Moss). What happens in reality....well, that's probably a different situation altogether.

 

ok...back to the original question. I have a 4S, not a turbo. I did exhaust and intake first. Improved overall sound.....little HP gain if at all. These mods are sold with a 10-20HP gain.....dunno if I noticed it...but that's ok. I later did an EVOMSit tune and headers. Maximized airflow.....big difference in power throughout the entire power band.
