'93 Talon TSI, Hit eco. button when drving?

[SLAMMED91]

Hey guys- For those that haven't seen my recent post about the TSI AWD I picked up, it also has HKS exhaust, intake, turbo timer, and boost controller.

I haven't even turned up the boost yet as I want to become a little more familiar with how the system works before toying around!
I am running at stock boost at this time.

It is an auto and I will use this as a daily driver so I would like to get "decent" gas mileage.

My question is- If I am driving around (easy, not punchin' it) in Economy and decide I want to kick it for some real action, will putting it in "Power" mode mess up anything. Basically, is it better to swith modes when at a stop than moving?

How about turning up the boost when I am driving, is the alright on the car?

it really only should change where your trans shifts at part throttle operation, it shouldn't mess anything up.

First things first, you say the car has a boost controller, but you say nothing about having a boost gauge. If it doesn't have one, get it, NOW. A buddy of mine had the same year of car and we used to tinker with the difference between the economy and the power setting. The only thing we found was the car would shift at 4500 tops in economy and the redline in power. Gas mileage stayed the same if you were easy on it in either setting. The one thing that I would suggest is that you come to a stop before you change it over. He switched it over once while just driving and it ran crappy for a couple of days and the shifting range was messed up.

The other thing is the tranny warning light. His car came stock with a transmission overheat light up with the light in the roof (I'm not sure if they all came with this or not). It proved invaluable b/c many times if he drove it hard, it would come on to warn him. I would also check and see when the tranny fluid was changed last.

You can hit the button at any time; it's a software input to the TCU and you can't screw anything up just by pushing it.

Can you imagine the class-action lawsuit that would result if you could break your car by pushing a button on the dashboard?

Definitely change the transmission fluid though. And forget "decent" gas mileage; these cars are much, much too much fun for that.

Not unless you've previously logged the car under similar circumstances and are certain that the boost level you "turn it up" to is safe.
