ok I have the performance tune programed in and since I have an o/r h pipe my check engine lite came on. well I disconnected the battery to reset the comp and went threw the programmer and turned off bank 1 and 2 and then turned off the OBII like it says in the book. then I changed the shift lite rpm to like 6100 rpm. well it said it was downloaded and everything but here it is a day later and the check engine lite came back on and the shift lite still comes on at 1800 rpms. what did I do wrong?
