If the BPC (APC) is working correctly and Posted by AdamB [Email] ![]() ![]() ![]() In Reply to: Re: 1.5 Bar is way too high for the stock turbo, Misha, Wed, 1 Oct 2003 07:51:31 Members do not see ads below this line. - Help Keep This Site Online - Signup |
wastegate is working correctly, the only thing other than the ECU and software itself that should influence the boost pressure, is the DI and plugs. It might get sense knocking falsely and reduce boost accordingly. A leak could give low boost too, but since you get 1.5 bar with the hose disconnected, I don't think that is the problem.
You can try and change the plugs (use NGK BCPR7ES-11) and if that doesn't work borrow a new DI. If this still doesn't work, I'd recommend you try and get another ECU or contact Speedparts atleast.
