Just installed new performance delivery valves I bought them at diesel fuel services in bangor It was an easy install. I had the 160HP low speed shutter. after the install the shutter is almost completly gone. probably if I had the diesel fuel services balance the barrels it would have been completely gone. the power has gone up. but egt is still ok the most I saw was 650 not towing anything. I feel it was money worth spent. oops sorry I put this in wrong topic
