Ah - I see we're really talking about two different "lags". I was only concerned with the "downshift to pass" lag. I'm literally a "Grandpa" and I've never felt the urge to stomp the thing pulling away from a dead stop!

Jack, the downshift to pass lag feels good to me. I don't stomp the truck from a dead stop either. I am refering to normal acceleration from stop. When I press the accelerator to go, say from a red light, it still takes the truck around 1 second to respond(prob more like 1/2 second but it feels like an eternity) and actually move. It is identical to the stock tune in this regard. Sorry I hope I am being more concise.

That IS interesting, Jerod. I've never noticed any kind of hesitation in a normal accelerate from a stop. That's really kind of weird! The transmission has to already be in first, and the torque converter is definitely unlocked, so the lag has to be in the engine's response to your throttle. My engine's response seems very "instant".

I'd definitely talk to Bill about this. I'm sure he will have some ideas.

Wonder if anyone else has experienced what you're describing - anybody?

That's kind of my feeling too, racinwarrior. I think I'd have to be careful starting out in mud or in snow.(But I guess locking it in 2nd, and 4WD should take care of things).

I have the 87 Performance tune and definitely felt an improvement in both dead stop and passing lag. I too am not really interested in nailing the throttle from a stop but have punched it for curiousity from a slow roll for fun. With about 25% throttle it will break the tires loose easily even at a roll. Passing is a pleasure, the truck just seems to set down and accelerate smoothly through the downshift and upshifts. Throttle is smooth and responsive without having to really hit it to get going like I did in stock tuning. Huge difference!

I drove my mom's 07 fx2 most of the day today and there is so much difference in the amount of throttle needed to get the truck to respond from a dead stop. Here truck is stock so I know something funky is going on with mine. I thought my truck would be as good or better than hers after the gryphon but that is not the case.
