Shudder when accelerating hard

[elieleb1303]

i should prob also mention that when i was puttin my bpv on today, i did notice a that in the tube that allows it to recirculate, there wasnt a tear but almost a spot that was stretched or cracked. could this be causing a problem?

hey guys about 2 weeks ago i put the su test pipe on my car, and last week i noticed it would studder a bit under acceleration. i figured it may have been from a boost leak i had, but today i installed a new cold pipe (due to a snapped bov bolt i couldnt get out) and when i was driving, i felt it studder in every gear while accelerating. my question is, if i take it to the dealership, should i take the tp off? i currently have the cat heat shield on it, but would it be smart to take it off?

Depends on your dealer. Alot of people play it safe and take mods off to avoid any hassle with getting warranty work. Some dealers won't troubleshoot if there are any aftermarket parts that might be related to the problem you're bring it in for.
