1/4 Mile Times Before And After Tune

[poopnewton]

I've read a lot people talking about what a difference a tune makes. Does anybody have actual 1/4 mile times with mph on their trunk going from a stock tune to a vendor tune with no other changes to their truck but the tune. Looking for trucks that are mostly stock. All I have is a CAI and different muffler.

good question id like to know too

[f1ss]

I know someone was pulling a 14.2 (or another tenth second) with a cai, flowmasters and 160 stat. Although I wouldnt recomended changing the t-stat, maybe to a 180 if your f/i or spraying...

For a stock truck, look to gain up to .4 on the high side and .15 on the low side...IMHO with all running conditions being the same.

Why wouldnt you change the thermostat?

I can see not changing it if you live somewhere up north. But if its hot as shit all year I would think its a good idea.

I changed mine back in 07 to a 160 no probs what so every. Drove it on some really cold mornings up in north fl 17 a few days and lots in the 20's and was still fine.

Back to Subject . Anybody got some actual numbers for their truck with factory tune and after a vendor tune.

Not doubting him but wanted to see real numbers with the mph difference. The fact that you added 60' times was really nice. Not that I am drag racing expert but at least I've been to the track enough to know that the easiest way to lower a et is by cutting down your 60' and that your mph is all about your hp. If all I got out of a tune was a .15 quicker et and the mph didn't really change I'd say it wasn't worth it. The 5 or 6 mph you got shows you got some horsepower out of it too.

I'll be dyno testing my 1500 hd(6l with 80e) with a stock tune and zippy tune back to back shortly to prove out hp gain. I estimate 20-30 hp with no mods to truck.

i remember mine ran a 15.0 stock and after a wheatley tune it was doing 14.7. ahhh the good ol days

[Silverad0 SS]

i ran stock with 14.9 and with the mods now i run 14.6

[diggerdan11]

I dont know the speed I ran for my Stock Run, but I ran a 15.2. With my tune I ran a 14.67 @ 91.5

 

Now those were at different tracks at different elevations, the first one being about 1300 ft and the second being about 200ft
