read everything on the boards new to this and getting familiar to tuner pro bought the APU1 have a bin from previous tuner and a data log. car hasn't run right since new motor put in March thought i would of enjoyed the summer after 10 years off the road didn't happen. its a 89 GTA maf 383 tpi, larger runners, 58 tb, vortec ported heads with 1.6 rockers and LT4 hot cam, long tube 1 3/4 headers, 255 walbro pump and now 30 lb injectors from 24lb. has a heated o2 and wb o2.

Car was running super lean not sure how much was false lean with the cam and more air going thru. the tuner had the 24lb injectors set with a flow rate of 20.9 and the car was final running a little better but didn't make sense to me. so i switch to 30lb injectors and now super rich but haven't switched flow rate or pulse width yet for the 30lb

any ideas help or advice would be greatly appreciated
