I am considering getting pullies. are they worth the $230 and heard the gains are about 10hp. Also should i do a 180* thermostat change and how much help will it do?

Concenses is the 180* is useless and the 160* is a good mod for FI only. You might want to consider a cam before these other mods.

I would put in the 160 stat, regardless of what my mod level was. You're in the South and it get's damn hot in the Summer. Your heater will run at a slightly lower temp, but still plenty hot to get/keep you warm in the Winter.

Getting tuning/logging software is a good plan.

Curious, why are you running TR-6 plugs? Do you spray your motor? I know they're the iridium version.

If you are thinking about a T-Stat you should go look in the southern section at the BB-mod how to

I dont get the t-stat mod. Where I live its been 105+ all summer and my truck constantly runs at 185. Which is on the stock tstat...why would you need any lower then that?

back to the question... one of my first mods were pulleys... couldnt be happier... you can definitely notice it from a dig and feel it a bit throughout the rpm range i would suggest it

It is a decent performance mod, but it will bring the sound level down from your system, and basically drain a lot of power from your accesories.

hmm didn't hurt mine none... did you get the bigger pulley for the alternator??
