Well, you've come to the right place for performance mods, but you might want to hide your wallet, because none of us seem to know when to stop :angel:
If you search around, there are tons of threads covering good initial mods. Everyone has their own slightly preferred combo/order, but this is what I would do if I was starting over in your place:
- "Trans safe" EFI Live tune. It won't be trans safe. You will blow your transmission up sooner or later.
- Start saving for when you blow up your transmission.
- Built transmission.
- Lift pump and a good tow tune, maybe a DSP2 with a hot tune for the weekends you aren't towing.
- EGR blocker plate, only really necessary with bigger tunes, IMO. No reason to delete it, just block it.
- Stop while you are ahead. Get a nice sports car or motorcycle to scratch the fast itch.
- Upgrade your turbo, something like the 68mm Stg2R VGT.
- Stop while you aren't that far down the rabbit hole, and still know what money feels like.
- A 4" (or 5" if you like it louder) exhaust actually starts to become worthwhile at this point.
- Injectors.
- Too late, you are one of us now. Kiss your wallet goodbye.
- Built motor.
- Crap, I've done it again. What even is money?
- "Twin" turbos (really compound turbos).
That's a nice looking truck, and you're going to love the LBZ! Welcome!
