Finally bought one 2004 GMC with 82K miles.
So I guess in the future I'm going to need help with some mods.
Like where to start first, best bang for the buck.

is it an lb7 or an lly motor? 8th digit in the vin will tell you if its a 1 its lb7 if its 2 its an lly

1st figure out your budget next figure out how far do you want to go,for programing efi live is the best,otherwise there are some nice canned tunes out there i like edge hot juice (150 h.p.) with the over head monitor.Your going to need a full exhaust,cold air kit.if its an lb7 for 30 bucks get the ppe boost valve,anything more and you are going to be sending your trans to the grave yard,also get a lift pump so you dont keep running the cp3 low on fuel.Take this for what it is,its my oppinion and there are some great people on here with alot more knowledge then me,these are things i have tryed and worked great for me.

LB7 I did manage to figure that out. 100-150 hp would be plenty, just want enough to surprise some people. Like to get a bit more turbo sound too. Air intake? Used to drive 18 wheeler so I kinda miss the whistle.

i would go with the edge hot juice,you can get the over head monitor that mount in the cubby hole you can power up or power down while moving and you dont have to plug in a tuner everytime you want to make a change the edge juice is 125 with the moniter and the hot jusice is 150 h.p. and get the ppe boost valve it makes a smaller orfice going to the waste gate and puts more turbo into the motor instead of letting it blow off

Port the turbo inlet, if you are mechanically inclined at all. This gives you more noticeable compressor sound, and allows the turbo to function more efficiently. Plus, its free.

Any info on this would be appreciated
