Bit of Advice plz
i have recently sorted various probs on my 1999 apy s3. it now runs ok but not quick quick like it should be. i have found out that when i disconnect the batt the car boosts properly (to about 14 psi and holds about 11) but after awhile of driving the boost drops to about a regular 10 psi and obviusly dosnt feel as quick. but as soon as i disconnect the batt its ok for a while. i have a n75 (J) on it wich is new. there are4 no fault codes, thinking the ecu is restricting its self?????
try disconnecting the maf sensor you may have a dodgy maf
