well going to get nelson tune should i get a 160 or 180 what do you guys use

 

I use a 160* with the whipple

 

I found out the stock truck stat is 186 or 187. I couldn't find an actual 180.

 

Use a 160. My Blown AV runs around 180 with the 160 installed....

 

Slp 160*

 

180 unless you're boosted

no reason to go 160 at all. Less power, worse gas milage.

 

Less power & worse gas mileage, I really hope you have something to back that up, because i've experienced neither of those two problems running a 160* for the past few years. The truck once warmed up will still typically be in the 180 range.

 

I'm kinda going to have to side with Trey on this one.
Not about the less power, but the worse MPG I agree on.
Not too sure how the 4.8 & 5.3L react to the 160* stat, but my VHO's LQ9 6.0L sure lost 1 mpg on average after dumping the factory stat for the SLP 160* stat.
It just takes way too long for the engine to warm up. During warm up it uses a tad more gas than when the engine is at close to normal operating temps.
Once it completely warms up, it does fine.
My 1/4mi times was 1/10th better after the 160* stat install. Could have just been a better run, but I didn't lose any 1/4mi time.
If I did it over, I would find out were to get a 170* stat.
A member here posted about finding one from somewhere, and it worked great for him.
Guess you would just need to do a little bit of research on it.

i have the 160' hypertech stat in my truck and did notice a slight drop in milage as well.

 

If I lost any gas milage it was slight. I went from stock 187 (ran 194) to a 160 (runs 172 now) I am running a tad more timing now and feels stronger all around. I'll keep an eye on my milage though...
