Hi all, wonder if anyone could help? My 97 sti is only boosting properly after an ecu reset, then after a while goes back to less responsive and the boost solonoide ticks on tick over. The garage have suggested putting in a manual boost gauge, old fashioned manual one? Any suggestion would be great. Also have brilliant contact for anyone out in Slough area for a fab scooby/performance mechanic. Very reasonable and knows his stuff. Thankyou
