Can someone please help point me in the right direction for my 4.8 GMC Sierra ?

I dont wanna void my warranty, but I do wanna make it a little stronger. All I have is a Magnaflow muffler lol.

Please all opinions and advice are welcomed!

UPD intake, ASP Pulleys, Electric fans, mid or full length headers, any kind of tuning will help. Look into a Predator programmer! Have fun! Good Luck!

 

I have read alot on here about the predator. Can you be specific on exactly what it does for me? Is it kinda like a hypertech?
My truck feels stout for what it is, however i was just wondering about some mods. Do the asp pullies kill voltage bad? I have a stereo that is kinda potent. Will the headers void my warranty?
is the volant cai the best out there?
I am in no way trying to be brash or synical, just asking honest questions so that I can make an educated decision on what mod(s) to do.

Thanks,

Brad

 

Oh and BTW, I already have a nitrous express wet kit and a Nos wet kit, But the Nos is on my 95 lt1 z. The nitrous express isnt really an option for me to be honest. I do not have a window switch nor do I have total trust in my factory clutch.

Ps. Is there any way to post an image of my truck in my sig?

 

The Predator will give you the ability to change shift formness, shift speed, increase hp and tq. You can adjust timing and that is just to name a few things. If you get the overdirve alternator pulley your voltage will staick the same as stock. Volant is a very good intake, but it seems UPD is very popular. And produces good results.
