There's always the Torque App. Haven't tried it yet but will probably get it in a few weeks.
I have to stop soon, I also got this car to save money........ last time I added it up I've dropped about $5k.........

Only crappy tunes will raise your rail pressure excessively. Rail pressure is a function of engine speed, so unless you are at high rpm, there is a limit to how much pressure you can generate from the pump. Please do not spread this disinformation. Talk to Malone tuning if you don't believe me.

Hmm, does anyone know what measuring block that would be in VCDS? Wouldn't be hard to log the difference between a stock and a tuned.

Not aware of any tunes on the market that increase fuel pressure over stock.
Quantity and timing can be changed without increasing pressure.

The ECU does all this, every tune i have seen on the market works within the stock parameters including EGTs. I don't care how many gauges you have you are not faster then the ecu is. Before you could even slightly detect something was off your car would have already detuned itself to keep things safe, this isn't the 60s with carbs.. hell this isn't even the late 90s with narrow band 02 sensors.
Gauges can be fun and they can be useful for diagnosis in some case but there is nothing a gauge will tell you that would make your car any safer because a modern ECU is just that good.

we haven't pin pointed the issue that some with DSGs are having with our tune where it pulls back right before a shift. Most likely it will require a DSG flash to maintain current power levels or it will require a detuned flash which most don't want.
I could be wrong but I think mostly they're changing the timing and length of the fuel delivery, not really the amount. (I know, if you drop fuel longer you're dropping more fuel overall but what I mean is that it's about the same amount of fuel sprayed, just longer or at a different interval than stock. Meaning, no nozzles or pump upgrades needed for a stage 1 and rail pressures remain the same)

That is correct stage 1 is pretty mild. Injectors and pumps are stock.

I appreciate the response. I am by no means an expert with tuning but how do we the end user know that our fuel pump is keeping up with the demands of a Stage 1 tune?
I apologize in advance if this sounds like a stupid question but from experience tuning my MS3, the fuel pump was the weak link with OTS tunes. The COBB AP was there for one to monitor this straight from the ECU which including datalogging to make sure you had a safe tune.
Read my post above. There are many fail safe and monitoring systems in the car, you'd get error codes when scanning the car if there were any problems, that's why tuners need people with vag-com to monitor their cars while in the testing phase.

Missed your post. So basically Stage 1 should work for every car with no issues? That sounds good to me.
Like I said I am coming from a car that needed constant monitoring because the Fuel Pump was not up to speed with a Stage 1 upgrade, so I am a little more cautious.

No tuner on the planet would be in business long if they produced an unsafe tune. A stage 1 tune from everyone is going to work within the factory safety parameters, you don't stay in business blowing things up.
If your fuel pressure wasn't keeping up the car would pull back power to stock or even below stock if need be. This would happen well before you could even detect there was a problem.
The fuel pump in the MS3 is the same one used in the early 2.0T applications and it had the same issues with keeping up with demand of a stage 1 tune that was a little to aggressive in the low rpms, so tuners detuned the vehicles to work around it. If the tune was a little too demanding there was a very noticeable drop in power as the car would shut itself down to keep things safe.
You can log all the info you want with VCDS before and after the flash if you want, you don't need actual gauges they are not worth the investment for daily use.

What is VCDS? Is it the VAGCOM I've read about?

VCDS is vagcoms new name after VW told Ross-tech (the manufacture) that they could not trade mark something with VAG in it.. they had no right really but it wasn't worth the fight.
