Installed Perrin top mount with Cobb stage 2 with helix downpipe and after installing intercooler noticed that when I accelerate hard and quickly let off the gas the car jerks and bucks. Is this just because of the intercooler on top of the stage 2 and it not being tuned with it?
Thanks

Yep, it's most likely your car's way of saying "That's about all the aftermarket parts I can handle before I'll need to be professionally tuned." Try giving your ECU a few days to re-learn what it needs to in order to run with your current setup and you'll probably be ok. I ran my car with an OTS Cobb Stage 2 map and GrimmSpeed modified headers w/ high flow crosspipe and a Turbo XS TMIC for a short period of time before getting protuned and I noticed similar symptoms when I really mashed the gas.

Should I disconnect the battery for some time or just clear the codes ( even tho there is no odes but It will delete the ecu so it had a fresh start to relearn)

You can do that.

But you need a tune.
