Hi Everyone -
For starters I want to say I just love my "Max", I am SO happy with him. I do have a question though. I have 392 miles on him so far. I am wondering about something, when I am going down the road at approx 45-50 mph and I go to pass someone in front of me it seems as though there isn't much power until the rpms come up and then it kicks in. I am not in od or tow mode, just regular driving. This has happened twice when someone was in front of me going too slow, I go to pass and it feels like it takes a few seconds for it to get up & go.
Is this a "dead spot" for lack of better wording that is what I am calling it. I am going to get an exhaust and eventually the Juice Box (I am wondering if this will help any dead spots?) but that is a few more miles down the road. Any thoughts or help on this would be greatly appreciated especially if there is something different I should be doing - driving a diesel like this is all new to me. So, I apologize in advance if this is a stupid question. (I will post a picture after my new wheels & tires get here).
Thanks,
Lisa

Turbo lag is probably a better term for it. When you step on the go pedal, more fuel is injected which builds more exhaust pressure which pushes more air through the turbo. It takes time though.

A box/programmer does help. I can't vouch for this but an exhaust is supposed to help too as it allows the exhaust to flow more freely out of the turbo.

Some of driving a turbo vehicle comes down to planning ahead. You get the feel for how long it takes and can have pressure built up when you're ready to go. It is not unlike forcing a kickdown in any other automatic.

Thanks Rockin, everything you said makes sense to me and now I know what the right term is too! As soon as I read your post it clicked in about the planning ahead it made perfect sense. I knew it had to be something simple since the truck runs so good overall. I know I'll be putting an exhaust on before the box so we'll see if that helps as well.

Come on guys. The wife need some expert advice.

Just to add to this, I have my stock exhaust straight piped and my turbo lag (dead spot) is no longer there... It pretty much just takes off instantly, without hesitation. Before installing a box, an aftermarket intake and exhaust would definitely help with the turbo lag and also make the exhaust gas temperatures (EGT's) drop quite a bit. I also have the edge juice/attitude, and it does help with instant acceleration, but the biggest factor is getting the air to flow better (w/ intake and exhaust)... hope this helps.

There Is A Pip# That I Can't Remember Right Now. In The Pip It Discribes These Same Symptoms. It Has To Do With A Throttle Pedal Positon Sensor. In The Pip It Tells The Tech To Drive Truck (with Customer) Then Drive Another Truck To Show That This Is A Charteristic Of The Truck. At The End Of The Pip It States There Is No Fix. According To Gm. My Truck Is A 04.5 And Does The Same Thing. Hope This Helps.

I saw a slight improvement in the turbo lag when I disconnected the EGR. You can give that a shot if you want to try something that is easy to do and easy to undo.

My 03 acts the same way Lisa and everyone I've drove acts the same way. Seems like theres a crossover point torque/horsepowere (my thouight) that theres a big power boost.
