Hi

I have a MY95 WRX, K&N Induction, BPM DP, BPM Center, BPM BB.

I am have noticed that my boost is not consistant. The BPM DP is a recent addition (last Saturday) up until then all was fine...

My car is now boosting to 16psi and holding at 12/13.... it used to hold at 14/15psi with the Magnex single dump (blank wastegate) and boost upto 17/18.

Do you think I could have a problem?

Also, I have noticed that on occasions, the boost would hold for a second then begin to climb.... I had not seen this before... again, could this be a problem?

It does not feel any slower than it did before, and I assume the only sure way to see would be a RR run?

Any thoughts?

Cheers

Paul

 

maybe bad petrol since getting the new dp?

id try resetting the ecu first

if you've filled up with petrol since getting the new dp, wait until you need to fill up, and then get 98ron(+octane too maybe) before resetting thou
