what 4.8t said

 

yeah we have support for 07's.

 

under power enrichment delay there are 5-10 parameters you can change for delay. FWIW the timer delay is overruled by the parameters we give you.

 

sweet thats a relief.. thanks. FWIW????

 

for what it's worth

 

I sent an email to Nelson to see what they had for 07 tuning and haven't got a reply yet. I also asked what the core charge would be , I would want keep my oe core for a new truck incase I end up back at the dealer. I suspect the core will be pricey,
I'll post up when I hear from Nelson's.

I also posted on the diabo forum to see what they have to say

oh....ok sorry i am a little slow.

 

sweet thanks. i'll see if i can find a tune on the repository thing. so i can take a look. so, stock does it delay timing too? because if its staying that lean at wot it would have to have low timing. right?

 

it doesnt delay timing but timing is generally pretty low on trucks as is

 

I asked diablo about tuning for nexgen and they have a programmer[part# u6194] and emailed a chart which happens to be this.........

Nice chart, big mid range improvement and big afr change

I called Nelson and they have tuning but have NO cores, they should have some before 2 long but will be pricey if you want to keep your oe pcm.
Hpt is still a good choice for those inclinced to learn tuning, sounds like there is some basic stuff to be done for the pe delay that would make a big improvement without getting too in depth.
edit.. did some reading at hpt, seems like the new pcms may be a bit challenging for a novice
