Custom tunes are better then a hand held the only problem is if you do things like change tire size often (20's for daily driving 16's W/slicks for the weekends) Or your going to use nitrous and want to dump your N/A tune a hand help tuner will much more convenient. A custom tune is more of a one shot deal.

 

I couldn't find prices on nelson's site...do I just email him to get a ballpark?

I am having a hellua a time deciding which intake. I am leaning towards an MIT and the stock box with a K&N, but have been contemplating a volant as well...just when I think I have decided I read another thread...

 

well maybe lol just buy an extra pcm for the slicks with the same tune, but my slicks never made the ses light to come on or anything else, hell my truck is set up to shift at a rpm not mph.

From a tuner standpoint ... there's not much timing to get out of an 87 octane tune. You can lean it out just a little and still keep it safe, which may give you some noticable benefit. The only thing a custom tune can do is remove torque management, which you will see a pretty good gain from. I think the Predator does remove some of the TQM, but still not all of it.

 

I was curious how much timing can you run on different octanes.

 

i am running a cam and im running 31* timing up top. but not till 5600 rpms.

 

On mine I run 29-31 depending on my IATs

what do you guys think about intakes? I had a K&N on my previous truck and liked the noise etc, and felt a gain, but my gas mileage, I think took a big hit. Would a volant be any better, or was it probably I just couldn't keep my foot out of it? So, I am looking at MIT and K&N with stock box, K&N FIPKII, or the volant without the scoop.
