Bogging/sputtering/bucking at WOT in 2nd

[ncampos92562]

Hey guys,

I've noticed recently that when I go wot in 2nd, the car starts to buck after about 4500rpms+. It will kind of drop off boost then come back, and over again until I shift. However, it doesn't do it in any other gear. Only 2nd.

I haven't really checked anything yet, but I'm going to dig into the plugs first and check the gap after I get a long enough extension for the wrench. No boost leaks that I can find.

So what could it be?

All mods are in my profile and I'm boosting 16psi.

It sounds like a boost leak. I would start there.

Yea check again for boost leak or try the plugs....do you have bigger fuel injectors if so maybe you need to upgrade to better plug wires or ignition
