I just recently purchased my first diesel truck. GMC 2500 HD and i love it.
---so, ya total newguy here.---
just how far should i go with the upgrades to my engine brfor i move on to the trans?

I am kinda worried about upgrading as far as warrenty is concerned though. Should i be?

How far should i go befor i start in on upgrading the tranny? i have already looked around anf the Suncoast Stage 4seems like it would be a good fit when i get up to 500 rwhp.

any thoughts/opiions are welcome

Cheers
