no i havent pulled them off yet. the twin CP3's are ATS and i have a stock lb7 CP3 with a LBZ reg. I also have the stock LB7 reg also. Im going to pull them of as soon as i get a plug for the fuel rail. Ive pretty much decided to keep the truck and turn it back into a DD. Just dont have the money to play right now for one and i need a truck i can tow with again. Im going to sell the dual fuelers, caltracs, and straight centerlink. I may also sell the 4094 and put a stocker back on and have it twinned with a S475 or something similar. I can keep my EGT's in check and still have a pretty quick truck that i can tow with.
