Ok my truck is extremely slow at opening up off the line. I believe that it has to do with the throttle managment and all that stuff, but if someone could guide me as to how to get my truck to move a little more off the line I would appreciate it.
4.8 that needs serious help off the line

turn off the PE delay and zero torque reduction if it's an automatic

Is that completely safe
pe delay is safe as is the other i think. At least mine is set up that way....
'04 ecsb Chevy: 4.8L turbo ,EFILive tuned
Post up your tune man.
Id defintelty start with reducing/removing the PE delay and lowering TM by 75-80%. Ive run 0TM and 0 shift times for the past year and 20K+ miles but Im an I6 and my TrailBlazer weighs less than your truck. I wouldnt recommend 0 TM unless you get your trans beefed a little.

I took off the PE delay and set the managment to zero and nothing was helped out at all...
I've had TM removed and 0 shift times for 4+ months and I'm running a ECSB w/ a L31 350 and have had no ill effects.Originally Posted by ScarabEpic22
Without seeing your tune, I'd say part (if not most of) the problem is probably your gearing. if you stepped it up to say 4.10s or something, it would probably help out a bit with the off the line speed, but would also increase your cruizing RPM's a bit, so its a give/take situation.
edit: you can also take off abuse mode too, its a form of torque management, I've had it off also w/o problems. post up your tune and we can probably help out more.

OK can anyone just send me a good 2003 4.8 tune that I can get some good gains out of if i send you my stock tune?
if you attach it to your post someone can probably take a look at it and give some better suggestions.

Is your truck electronic thottle. Make sure the PE delay is off. Off the line for a stock truck dosent need to be very rich at all 12.8-13.5 off the line but don't add to much timing over stock for a leaner PE becuase you don't need it.
Electronic throttle porbably might have something to do with it but I don't have any experience with ETC.
