The base BOV can cause it to surge

When you say stepping on the gas, are you in like 4th gear and going wot at 2900 rpm? Or are you in 2nd? A little more clarity on gear and rpm would help. It it a high gear, low RPM situation it will buck hard for a number of reasons.

What size vacuum line are you running to the BOV? I'm running a 4mm hose and I read that Tial recommends a 6mm line. I think mine is staying slightly open when getting into boost and I'm bleeding it off due to it.

I also have a tial bov. Not sure what size vacuum line. But it does in 3rd, 4th and 5th gear. I have lund tune. Haven't talked to them yet cuzz I'm getting 3.33 pulley and wastegate installed soon so I'll get a revised tune and see.

You know.. I've never had this issue before until the other day. I installed a new McLeod clutch/flywheel so I was thinking it had something to do with that since I was having problems with getting air out of the system. It was 4th gear, -2K RPM.. It was jerking the car back and forth.. wouldn't stop with acceleration, so I took it out of gear and back in. It's done this twice to me in 2 days.

Hey guys check all your vaccum hoses going to imrc valves,also u can do a key on engine off check and make sure the actuators are moving on the back of the manifold.This will cause a surging/bucking issue.

I know what u mean about bleeding the clutch lol,about 250 slow pumps of the pedal before i had enough pedal to get the car into gear!!!.Real pain in the ass!!!.But pedal is great now.
