I recently purchased a 99 3500 cummins. Looking to add a few mods . Engine is stock , but I've added an edge comp and the insight cts . Thinking about bigger stocks and latter a bigger turbo . Any suggestions?

 

What trans do you have ?
If auto I would upgrade that first.

 

welcome to db
You should upgrade the air filter and exhaust to something better before going bigger sticks or turbo.
you will want to help the motor get more air in first end get the exhaust out easier, than increasing the fueling first. That causes the egt's to rise quicker.

 

It has a 5 speed manual transmission and the exhaust is a flow master 4 1/2 from turbo back . Getting new air filter system this week

 

Thanks for joining
