ok heres a scenerio....i installed my TXS short ram intake yesturday and i decided to go out for a spin....nice turbo spool up sound, i was throttling it and then my car stalls when it shifts gears then i felt this abrupt pull like someone just threw a hammer undar my car everything in my car vibrated.....it happened 4 times in a row, i dunno if im knocking or if my TC slipping, i also failed to mention that i have a oil leak from my valve gasket.

this seems to happen only when it shifts to 2nd gear it shift gears then pulls the car hard and i hear a sort of thunk like all my change and stuff in my car

 

bump for help please
