Just installed the TW chip, some questions.
Well I was sick of driving my truck stock so I was excited when the TW chip came. I'm not sure if this is normal but in eco tune the shift point seem the same as the rest of the tunes and they all seem to shift around 2000rpms
so besides the Eco tune shifting the same as the tow tune they all also will not shift up at around 45 mph, the RPM's are the same at 47MPH as they are at 70mph. Is this normal, is there a reason for this?
Also when the truck does shift into overdrive at a little over 50mph if I slow down close to 45 again it will down shift and throw it back up to around 1800rpm so basically if I am on a street that has a 45mph speed limit then I'm spinning at 18-1900 rpms, just like on the highway at 70mph. you would think the economy tune would shift for often to keep rpms low.
My dad had chip tuned at the same time as mine so If his acts the same way I guess its normal, but figures that while I was installing the chip I noticed his brake fluid reservoir was empty and a line blew so we couldn't test drive it.
I will take a short video later
