I had GIAC flashed on my 05 GTI about 2 yrs ago. I thought it was about time to check to see if there had been any software updates. I had the shop reflash with the newest version yesterday, and now I feel like I've lost a lot of power. Before the upgrade, when I pinned the pedal in second or third, I'd be pushed back in my seat, get a little tire chirp, and take off. Now, it feels more stock-like. It's a smooth delivery, but it's lost that push-into-the-seat fast feeling. Anyone have ideas?
To preempt some possible questions.. I chose to upgrade even though I loved what I already had in the hopes that I would lose some unfriendly surging and possibly my CEL. So far, both those things are gone.

Your new version has what they call "n75 smoothing" to keep the car from hiccuping and surging. Its designed to work with the stock n75F valve. I don't know if your previous program had that or not, but that could possibly be it.

I don't think my previous version had that. But even then, would some smoothing effort really make this much difference? I have an N75J waiting for me to have the time to put it on.. I wonder how much difference that will make, now.
Other thoughts?

In the time it takes to post here, you could've already had it on. It doesn't take that long

unitronics = compatible with Big turbo's
giac x+ = stock turbo

i have the 14c program and i feel that its too smooth for me.
i put in a n75j valve and the car had days where it boosted hard and other days as if i had no turbo on the car and was towing a trailer behind me.

i would have to say the same for my GIACx+, there are days when indeed it pulls VERY HARD, surging never seems to be a problem until the higher gears..
Then there are the days where it doenst pull very hard, or like he said, an hour later you wondering where it went. But it always comes back.

Push the right most pedal harder. but for real i have heard it adds a couple more HP and a couple more TQ but it has more of a gradual curve. Its not 10more or whatever that hits you even harder. its just more power and more gradual. just waht i have heard tho. contact the company that did the reflash. and ask them why you have lost the "push-you-into-your-seat" feel LOL thats funny sorry. http://****************.com/smile/emthup.gif
