850 boost problem
Hello,
I bought few weeks back an old t5 it´s 1994 model and previous owner has fitted it with full exhaust system and somekind of a chip. However it seems like it is not boosting what it should. Original boost gauge hardly moves over the middle section.. So i thought it might be some cheap chip and bought a chip that is known to give a boost peak of 1,2 bar, but it is exatcly the same like before. I have checked the fault codes even though fault light wasn´t on. Got these codes 1-2-2 and 2-3-1 so i assume it gets the extra fuel needed for extra boost? 1-2-2 code i don´t understant since 1-2-2 shouldn´t be on turbos? The cars does not smoke or anything like that.. What to check next? Can this problem be maf related?
