Hi there

What downpipe you are running and what exhaust you are running,hope so you are not running those cheap DP and Exhaust from eBay?!

What headers or Up pipe you are running,do you running standard headers and Up pipe?

If you are hit full boost at this level,I would suspect you must have boost leak somewhere or can be just your exhaust is blowing etc.this can cause bad/slow spool up

Im not sure what make it is as i bought the car already like it mate, its a 3inch i think or as close to that it is large n so it the whole exhaust system n headers n up pipe are standard and not been touched, its not blowing as ive checked everywhere and had a garage double check and then it passed mot no problem, it has a fmic though hks induction kit and baileys bov, apart from that the car is standard.. Im not sure if its been mapped as previous owner had done the work and said its been mapped but lost the printout :-s.. Trying everything to get it sorted but not getting anywhere at the min :-s as far as boost leak ive checked all pipes and they seem to be fine, it still hits full boost at 1.1 bar just doesnt hit that until 4500rpm :-(

Hi there

I would suspect if hasn't been mapped this can be the problem,because without the mapping FMIC can be cause of the lag and Downpipe shouldn't cause those problem,if its half good as some Downpipe on the market.Plus Induction kit without the mapping can result in big problems.Speak here to mappers and ask them if can check the is your car been mapped or not

Try remove Bailey DV,those Bailey DV I wouldn't run on the Subaru,they are worst,because usually leaking etc


Hope you get this sorted
