2G Talon TSi Bogging Issue

[TurboTsiThatFly]

I've noticed that in 2nd gear about 2800 to 3000 rpm if i got w.o.t. It feels like it bogs. (Some times it does it more than once.) But if i let off the gas and go back into it it will pull like normal. What could cause this?

Have you checked your plugs,wires,fuel filter and air filter?
Lets start with the simple thing first.

brand new filter, plugs, wires, idk about my fuel filter. how often should the fuel filter be replaced? cause the car has 138xxx miles on it. and i know ive never changed it.

Check for boost leaks or air leaks after the mas before the turbo.I have seen tons of loose stock intakes or a vaccum line coming of the intake causing similar "bog" issues.

Chances are the fuel filter has never been changed. I would change it.
Alot of times a bog when you go wot is a failing fuel pump or fuel filter.
Since you say you changed the other things.
Have you looked for vacume or boost leaks?

Do a boost leak test (at the turbo and at the throttle body). Changing the fuel filter wouldn't hurt either.

What plugs did you put in and what'd you gap them to?

Plugs are gapped .28 there ngk plugs. I had minor boost leaks before and i fixed them. Maybe i have another boost leak. I guess im going to try replaceing the fuel filter and seeing if that helps to cure the problem.

On Another note my mechanic told me that me having such a low thermostat. That the car could be taking power away cause the computer doesn't see the temperatures its supposed to read. Could this be true?

I had the same bogging issue. I would slam the pedal and it would bog, then I would let off at it would be fine. In my case, it was a combination of boost leaks and timing. I think the timing had more to do with it. The cams were off by 1 tooth so I re-did the timing belt (second rate garage did it before I got the car), fixed my boost leaks and no more bogging!! So, check your timing both with a light and physical cam-shaft alignment as well as a boost leak test. -Jeremy

How low of a thermostat are you running?

I think my thermostat is a 160 degree but im not sure. and i have to replace my water pump soon. so im just goin to do a timing belt job then also.
