Re: Re: (Sue Esponte)
Eric,
Not sure if I would use one person's experince as a proxy for GIAC. They are well known for having very well tested maps, and also usually two different levels, more or less aggressive. I had their chip in my old S4 ('01) and went for the -X (=more aggressive). Very nice upgrade with lots of torque and high end HP.
I remember seeing one quote that summarizes the chip & turbo failure relation perfectly:
"No, there is really no problem at all pushing the turbos to deliver twice the orginal design pressure and volume. Really. I'm sure."
IF you chip THEN your engine will be further abused
IF your engine is further abused THEN things will break.
The S4 (B5 style) was a rare bird since the RS4 model in Europe was pretty much the same engine with larger turbos and larger ICs. Hence the rest of the engine and drivetrain could easily take the chipped power.
On our cars I'd be concerned not only with the turbo, but also with drivetrain movement, the angle gear, and the intercooler (pressured air) piping etc.
But if I could get the same rush I had in the S4 in the Volvo - SIGN ME UP!!

As noted, GIAC has always been an aggressive tuner of VAG cars, but I've known VAG owners who have run into issues with some of their tunes...which gives me some pause in consideration of their response to question #1. My friend was pushing a lot of oil through his exhaust with the original chip in his TT. It was fixed but if the Volvo program isn't being supported then I'm concerned. -Eric |
