im not doubting that at all.

as i wrote it depends on the conditions, weather, temperature etc. it can range from 14.5 psi to 16.7 psi.

JhnR · 10-24-2010, 01:42 PM

did you dyno by any chance?

enrita · 10-24-2010, 01:51 PM

364 whp with STage 2 (here was about 1 C and was boosting 14.5 psi)
Stage 3 mods stock boost 272 whp.
Completely Stock 251 whp

From the GIAC website on the Stage 1 tune:

"For optimum performance the software must be coupled with exhaust and intercooler."

So the car should not have catless downpipes for Stage 1, but the rest of bolt-ons are ok ?

I had the stage 1 race for about a week (before I went to stage 2 race) and the thing was a complete animal. The only difference was that the RPMs, although they raised quickly, seemed to be sort of strained to do the stock downpipes. So it was semi-struggling to rev. With that said, if you can, just go stage 2 and you will not be disappointed. TRUST me.

How long would it take to upload the stage 2 map after I already had stage 1 in the car ... ?

The reason is I am installing my Downpipes at another shop once I get my car back on Friday and then was thinking abt getting the Stage 2 uploaded. I will drive it without DPs on stage 1 for a week to test the car out first. I think this is a better option since you only need to pay another $200 to get the new software.

Thanks

Thanks

same as stage 1, around 40 min. i would just wait to get the dps installed and get straight away stage 2 instead of stage 1.

Yeah but then I don't get to enjoy the extra power for a week ... haha. But I guess I could do stage 2 before I get the DP ...? But don't thing that would be wise. Thanks for the responses everyone.

GIAC is not going to flash you stage 2 with the stock dps in place. Just wait one week...

sleepergm · 10-28-2010, 04:58 AM

Got an email back from GIAC ... and they said that the car will run great with all the mods. Stage 2 is just a calibration that is specific to a set of mods and so that one can get the full power that can be offered.

Well thats great news! means they have fixed stage 1 to fit modded and unmodded. Really good!
You are going to last 2 weeks with stage 1 and than you will start thinking why the hell didnt i get stage 2

sleepergm · 10-28-2010, 08:57 AM

Yeah your right ... but doesnt really matter since stage 2 cost $1000 and stage 1 $800 ... and I can upgrade for $200 so I only loose time for install. I have to wait for the downpipes to be installed too ...

But I get the stage 1 back tomorrow along with new suspension, BBK, Exhaust, FMIC, DV's, DCI, Vorsteiner kit for M-Tech. Then I need to do stage 2 and LSD.

Cant wait ... and update with photos coming.

"1+" as it is referenced, is actually a file for use with an upgraded FMIC, and factory DPs. I must admit that I am trying quite hard to keep it underwraps in an effort to control excitement/impatience=>

You ABSOLUTELY can run stage 1 with full bolt ons..as a matter of fact since GIAC is torque targeting you will see even lower boost than 14psi and wastegate duty cycles in the low 20% range..it a great way to make good power and run the engine and turbos effortlessly.

Mr 5 dynoed his stage 1 with full bolt ons and was making ~370 hp at 13.5psi
