Hey guys this is the first truck I have owned and I want to up the horsepower but not enough to where I need to get transmission kits or an after market turbo. Ok so I got a 2003 chevy duramax crew cab short bed, I have a k&n intake, arp head studs, and a turbo back exhaust to 4 inches and a boost gauge. i was wondering what I could get to add some more power.


Someone I know has a 07 duramax and they have around 505 horsepower and have these mods: banks intake, 5inch straight pipe exhaust, egr delete, efi live with a DSL 5 switch and running gauges an edge cts in sight and an air dog lift pump,

What would you guys recommend I should add to my truck? Thanks a lot

 

You have the air and exhaust part done. So you could look into a good tuner for your rig next. And one that has the gauges part built into it.

 

okay thanks for getting back to me, have you used any good tuners that you liked? or would recommend ?

 

I have a 12valve so I have none on my truck.
But efi live is one of the best out there, spendy but a good system.
Another one is the smarty, and smarty jr.
and you also have the edge.
you can also ask your friend what he thinks of his tuners for his truck.

 

Okay thank you for the information I appreciate it

 

2x for Efi Live

 

Ok I will look it up online thank you
