[QUOTE="blazen71, post: 16943155, member: 77485"] I had a Tial BOV sitting on the shelf so I went full OCD and it worked out perfect! I bought a $50 Diesel Turbo timer off of ebay to control the Tial. The timer gets input from the TPS. When it see's a rapid decrease in voltage it triggers a 12V signal to the normally closed MAC vacuum solenoid and opens the Tial for about 1 second. This allows me to run a smaller more restrictive pneumatic muffler for normal driving making it whisper quiet and then when I let off the throttle after boost the Tial opens. An added plus that I didn't expect was when I pulled the circuit board out of the Diesel turbo timer it has a rheostat for sensitivity to the voltage drop from the TPS. I turned that all the way down. Keep in mind that the Tial is a secondary BOV after the pneumatic muffler. My main BOV is the Big Red Procharger BOV and that functions as normal. [/QUOTE]
