I've been running a Flashpaq for quite a while and had not bothered to update it since I first installed it. Last week I decided to update and all I can say is WOW!
It made a helluva difference!
I run the 87 octane tune (yes I'm cheap) with 87 octane gas. Before it would ping under load, now I only had very minor pinging when it's over 100 degrees out. There's also a setting for improved throttle response. Overall it's a lot better and the old tune was a big step up over stock.
So if you haven't updated lately take the time!
