Maybe your getting use to all that power and it doesn't feel suprisingly strong like it did, now you'll be wanting more I'd think YOU could lite them up whenever you wanted, passing cars with your back wheels smokin must be nice.

 

You may just be picking up some knock and it is throwing it into the low octane spark table. Could be caused from a bad tank of gas.

 

It could be that. California gas sucks, for sure. That's what it feels like, like the timing was retarded/pulled. I wish I had some software to monitor...on my list of things I need

 

Maybe burst knock with the rapid airflow change?

 

Set your 4rth to 3rd kickdown to a lower tps % (45%-50%), thats how I fixed it. In 4rth, converter locked, if I give it just a little pedal it downshifts to 3rd and pulls real nice. Table D0962

 

your going crazy is my guess...... you are subconsciously looking for a reason to mod more.... junky get yourself some help

 

Sounds like your truck is no different than a women...............

Hey, talking niceley works.....


I like the sound of the burst knock being your problem....

 

What is the least expensive software I can buy that would difinitively answer this question? Do I need the full version of HPT just to log?

Ps. Can you explain burst knock?

 

I can log your truck with-out a license, but yes once the scan only option is released from HPtuners you could just go that route..

Burst knock~ predicts knock and pulls timing to
prevent it. Usally happens when there is a huge transition in TP, like going from 20% throttle to WOT. The PCM uses a combination of the maf and V.E tabble durring this time too, so if your maf and v.e tabbles are tunned well you shouldn't have to much burst k.r. Some have said that a rough v.e will also trip burst knock. But basically it is to prevent tip in kr....
Did I miss anything Dewey?
