Fixed the knocking, but a lag acometh at full throttle start

[orspg]

Lew, I did the -3 spark retard at the highest rpm, like you said and it fixed the knocking in first gear, and only a little in second, but it has terrible "on it" throttle response. How can I improve that to be almost immediate? It looses about a .5-.8 sec in a "bwaaaaaa" (sorry, but everyone knows what I mean) at start then it jsut takes off! Is there a trick to get it right on?

I clocked a 7.91 at a 6% grade uphill for a 6000lb truck. I think it's pretty good, but I'd like faster, please! Thanks!!!!!

Is this on the Escalade or the Silverado?
They are both electronic throttle control setup's right?

It's the Silverado. It's like the old days of over rich carb. Part throttle works great, but full throttle fells like it's "drowning", catches it's breath, then takes off! and yes they are both electronic throttle setups.

orspg, can you do a new WOT log and post it up! add inlet air temp and o2 sensors please... from your last WOT log (which I had to go hunting for, stick to one thread) there are many descrepincies. Lets see if they are consistant and what can be adjusted.

Actually, just gave the 2500 HD truck back to the dealer and ordered a 2011 duramax 3500HD dually with allison tranny. However, I am SURE that diablo doesn't support that yet! Right? or hopefully misinformed!

They changed the PCM in the 2011 dmax, so we dont have it supported...yet.
