Well, a buddy of mine has a BDDL w/CL that I sold him several months ago. Its ran awesome since he's had it. Well, I've always thought his truck felt stronger with the CL than mine does with the TST/EZ, DDP sticks and SP66. So tonight I installed his downloader on my truck. CL+TST on 0=very weak, tons of smoke. CL+TST on 4/2=even weaker, even more smoke(like a freakin freight train). Egts wouldn't go over 1200 degrees. I can hit 1700 degrees with the TST and DDP sticks. Boost #'s were also low. So I installed the downloader back on his truck. Now his truck runs like crap. A lot weaker than before. His truck normally hits 38 psi with the CL, now it only hits 30psi and only 1200 degrees. What happened? Did the Downloader damage our computers? Or is the downloader fried? My truck has a rail cap, but his doesn't. So I know thats not the problem on mine. Any ideas?
