Sounds like you're just experiencing the stock truck power. It'll tow what you got, but it won't be anything fancy. Like @Me78569 said, you start replacing injectors, changing out your torque converter and valve body, tuner, things liven up real quick!

Locked 2nd doesn't drop the RPMs as much as you might think. I've had Jon work his magic on my VB and when locking in 2nd it maybe drops the RPMs 500 +/- a few. Mainly comes in handy if towing up a slow grade and you're looking to keep the trans temp down by keeping the TC locked, or vice versa, coming down a similar grade.

What coolant are you running John?

Bluetop here as well. Zero complaints with the box or customer service from Ryan! https://www.bluetopsteeringgears.com/history

Sorry for the delay. I went from a 2in spacer to a 1in spacer from daystar and I didn’t need to adjust anything other then the steering wheel alignment. Everything else felt the same.

I select whatever setting I’m going to use before I start ifnim going to use 6 or 3 cylinder modes. If I’m going to use mpg and truck is cold (like sat overnight cold) I start with the switch off then select mpg as I get driving. I then leave it in MPG the rest of the day.

I'm not sure it's explicitly spelled out to explain what we're talking about, but it's tricking the IAT's and ECT's to thinking they're hotter/colder (as applicable) then they actually are, so it'll have change things in that sense.

Yea man, if you’re leaving your switch in MPG setting then you’re telling the IAT sensor it’s warm out and no need to cycle grids, which is why your WTS light is going out so quick and why it’s stumbling a little bit when it’s colder out. Mine will do the same and it’s not even as cold here as you’re seeing. I’ll typically turn mine to MPG after the first start of the day and leave it like that all day, then back to off after last shut down for the night.

Valve body

If you’re planning on 450-500hp you’re definitely going to want a triple disc. Most trans builders recommend a triple even with stock power rebuilds. If you’re trying to save money the HD flex plate wouldn’t be absolutely necessary given your current one is still in good shape.

Yea I think for 450-500 you’d be lookin at more then a 3500 dollar trans. Plus since you’d need to ship internationally that would only add up the total.

Go with genuine Bosch RV275s

Jeez! I didn't even know they've been around that long! I may need to pick your brain on some stuff!! Those timberlines are serious cash that's for sure. I was able to get a good deal on a pro 22, which is probably more than I need but that's a good thing when it comes to these!

DO IT!
