took car out this morning for some 1/4 mile runs on our local "strip"
DTC off, car in manual mode, starting out in M1, shifting about 6000-6500....wow it ran good...for stock anyways. didn't hesitate, didn't surge, pulled hard.... big difference from leaving it in normal automatic drive.
so what would this test tell me? something up with the trans if its surging and hesitating in normal automatic mode? but not in manual M1-M6 shifting myself? weird.
only thing I did notice when manual shifting is between gears the cars RPM's would drop significantly, like 1,500 rpm's...for example between each gear I would shift at 6500 it would fall back to around 5000 rpm's.... is that normal? can I take that lag out with tuning? on my turbo buick cars grand nationals etc...the rpms fall very little if any between shifts...or my wifes mustang gt doesn't fall rpm's either...
any thoughts on above??? thanks guys.
