do I HAVE to have gauges to run the chip if i run it easy?

 

I would at least have an EGT gauge. It's like running with scissors, Sure, lots of kids do it and make it out, but why play that game?

 

haha ok thanks, and I just bought a TS chip and im dying to use it, but I have a stock exhaust will cause too much back pressure?

 

Back pressure is not the worry as much as EGT's...

 

So I can run a stock exhaust?

 

Stock SD exhaust is not that bad, a good 4" turbo back will help, but your not dealing with the smashed down pipe like the OBS trucks have.

Remove the muffler and cat (if you have one) and that is 80% of the restriction.

 

alright thanks hopefully i will have it all soon

Probably not... Still could have PMR's...
