I have a 2007 new style gmc sierra 4x4 with 5.3L . I am running a high octane tune,TM disabled. The truck still seems a little doggy off the line. Is there any way to get more low end from adjusting the timing? I'd appreciate some advice.

just do what they told me to do in my post. you need to tune pe but before you start turn off cot protection.
There is alot of power left on the table.
Spark needs work along with fuel.
Why is the AFR correction adder zero'ed out!!
hmmm...PE delay is at 2000rpm. Enrichment rate I changed to 1.5 Not sure why the afr correction is like that. I had a Diablo tuner before I bought the HPT, all I did was modify the diablo tune with HPT, So that's probably why. What should it be at? Thanks for the help guys! I copied the AFR correction table from the stock tune and turned COT off. Let me know what you think so far, sorry I'm still new at this. Not sure how to go about adjusting the spark table.

thanks alot! I'll enter those in and i'll let you know how it goes!
is there an easier way for me to enter them in other than entering the numbers one by one. any way for you to post a new tune with the updated tables?
Because it's in a thumbnail no. But I just made that table to give you a general idea of what you can get away with. Just make your tables look relatively like that and adjust accordingly compared to KR. It's a trial and error sort of thing.

Your IAT spark table should look really close to mine though.

I'm brand new to this forum and have registered. This is an old thread, but is there a way I can open the attachments? I think the answer to my low power at take off is answered here. I appreciate any help.
