My dealer did the EVO intake and the GIAC software flash on my 03 996tt. What BAR should I be expecting to see? It seems sometimes it's 1.2 and other times only up to 1.0-1.1. I just installed some EVO diverter valves as well, just to be safe I guess, and tonight I thought I saw 1.2. However, then I could only muster up 1.0 for the next few runs. Also, I know this is going to sound dumb, but is there supposed to be remnants of oil in all of those lines/tubes I had to disconnect to do the diverter job? Thanks for any info.

You should see 1.1 t0 1.2. Are you checking this under full load and in third fourth gear?

Well we need just a bit more info. What turbos do you have (or any other info on your car)? Don't look at spikes, look at sustained. This can be seen with 3rd or 4th WOT runs. Should probably be 1.0-1.1.

How much hp difference is between Giac Stage I vs. Stage II? I have a 02 996tt with k16s. I have a flat panel K&N and Bailey's diverter valves. I know that stage II requires an aftermarket exaust. Any insights will be greatly appreciated. How much bar should I see in Stage I vs Stage II?

Thanks!

I have GIAC Stage 2 software with a Europipe Stage 2 exhaust, and get 1.1 to 1.2 bar at WOT depending on the gear, the starting RPM, and the grade of the road.

Savage

wow, great replies thanks! I have k16s, GIAC(stage?). EVO diverters, EVO intake and headers. I had purchased an exhuast, but it was just too loud for daily use, sounded great if it was strictly track car. i'll try the fabspeed 3rd gen when I make another sale. I'll try the 3rd and 4th gear runs.
thanks again

You mentioned that the exaust was just too loud for everyday use. That's what i'm very worried about. you have fabspeed maxflo gen 1 right?

I have k16s, GIAC(stage2). EVO diverters, EVO intake and Europipe Stage2 quiet. I see 1.1 everytime but have never seen 1.2. I'm also in California where it doesn't get super cold..

i'm leaning to just go Stage I, but i'm worried that i'll be disappointed. Is there a big difference between GIAC Stage I vs Stage 2?

Mr C

Send Kevin@UMW on here an email, you won't be disappointed by his 1 Bar flash upgrade!!!

No that is the same code. Unfortunately "stages" are not universal and can mean different things (tuner dependent)...usually the difference between stage 1 & 2 is hardware, not software.

Something to be considered...it is NOT all abut boost. It is about power. So if your temps are too high, you get nothing with the extra boost. You need 2 things air (preferably cool) and fuel. These combine and combust with a spark. Certainly if you can pack more of this into the cylinders (e.g., boost), then you can get more power (provided the fuel does not pre-detonate). However if the air is hot, combustion is compromised and you get less power. So the key is combining your hardware (turbos, intake, exhaust, etc.) with appropriate software (timing, AFRs, etc.).

GIAC is quite good for what it is...an off the shelf ECU modification. For true optimization, the tuner needs to know your components and the environment you drive in. FWIW.

Dock

Yes, GIAC is pretty good...as is the software from some of the other Tuners. And I would also say that the GIAC software is designed based on the car's components...for instance my GIAC Stage 2 software assumes stock engine components (K16 turbos) with a free flowing aftermarket exhaust.

Savage

No, it was a knockoff exhaust, 2 can system.

wross996tt

Sorry this makes NO sense...assuming does not mean knowing. Just as I was saying GIAC is off the shelf and is written regardless of what the user has installed (assumed or not).

Dock

So you think my Stage 2 was written for K24 turbos?
