I've recently noticed on my newly aquired 2009 Silverado that during normal street driving on my 4-5 shift, there is a delay, then rpms increase 200 rpm before the shift completes and rpm's drop down. Is this what you guys call shift flare? This is happening on BOTH my stock tune and a tune I purchased. On my purchased tune the pressures had been increased by 60 psi across the board and it shifts the same as the stock tune. Stock tune is posted below. Maybe someone can tell me if I need to increase/decrease pressures in maybe the apply/release for the 4-5 shift.. Or maybe this is NORMAL? Thank you.
