Getting a hesitation at around 1500-1700rpm while accelerating and when it's on over run coming down the revs. Searched and sounds like the egr gasket problem the blt suffers with but mines a asz.

The only thing I've done to it prior to this starting is the elephant mod but the 19mm pipe in had wasn't long enough so put some airline inside it to make it longer, could this cause a hesitation?? I think that's just a coincidence personally but I'm hoping one of you lot might know. Thanks

Get your egr valve off could be blocked up and give it a good clean.

I did give it a clean when I did the elephant mod but will try again
