Ok, I've searched and got some basic info, but just want to check a couple things.

Truck - 2008 RCSB 5.3 completely stock (for now) with a Radix 112HH (stock pulley is a 3.6"). I am planning on doing LT's, catless mids, and custom catback in the next 30 days or so. I just got HPTuners, havent even loaded it on my laptop yet. I was thinking about going to a 3.0-3.2" pulley, but don't want to back myself into _needing_ meth. I also do not have a wideband yet, and am wondering if I can tune it to get it in the ballpark without one, until I get the exhaust on. I'd rather not spend alot of time trying to tune the truck knowing it's going to change in the next 30 days or so. This is my DD.

I have the "stock" HPTuners file, and the maggie version. Am I going to be able to compare the 2 files, and scale some of the changes to get me close? Keep in mind, I have never used HPT before. I have downloaded several of the tuning guides that I will eventually read through to learn the tuning process, but was hoping to not have to be so "thorough" with just a pulley change.

Sorry for the book

 

Nothing?

I was hoping for an answer like "sure, just scale x tables that were changed with the maggie tune and that should be a good starting point" or something like that

If not, I'll just have to wait till I can get a wideband.

 

Get a w/b on there
