It was ok as expected....with the exception that the tach took a crap and had me lifting way before I wanted to lift....but I got the information we needed to start the tuning and adjustment phase......

did 2 runs and lifted well before 5000 rpm tach was showing 8000 rpm but the numbers were at 9psi 1st run: 243 RWHP/317 FTLB TRQE...but lifted at 4900 rpms.........2nd run: 251 RWHP/331 FTLB TRQE....would have made more but lifted at 4100 rpms............but the dyno shows very very rich through out the rev range.....not good but not bad...

Ok I have a 1991 325is I must know is this turbo thing going to work out? What kind of internal mods have you done? how much has it cost you so far?? I have to do this! after I convert to mass air I think that would make it easier to tune! No need for seperate fuel management?!@ How much did it all cost with out the secondary fuel management?? THANKS IN ADVANCE FOR ALOL YOUR CONTINUED HELP AND SUPPORT! I NEED BOOST~! LOL
