So needless to say, I'll be shopping for RV275s and finally installing that 4" exhaust that has been sitting in a box in my garage. Hopefully that will help.

Thanks guys, Mike.
Sounds like you got it figured out .
The exhaust and injectors should make a nice addition. If you don't have a box/module of any type then you may need to get a boost fooler when you install the injectors.
Bigger injectors=More fuel=More boost. I'm not sure if the RV275's will make enough difference, but if you start throwing an Overboost code after installing the injectors then you will probably need a boost fooler.
Let us know how it works out.

Doohhh!! I forgot you've got the VA box, you should be good on the boost fooler thingymabob.

Right, thanks man. I do have a boost elbow, too. So what do you think?? With RV275s, the VA and a 4" exhaust and boost elbow, I should be around 300hp/650tq?

I know it's hard to say but I just want something so it's not such a dog. Would like to get as much out of the HX35 without changing it.

Hard to tell HP wise, but that should be a good set-up with the HX35.
The HX35 will handle those injectors just fine.
You should get a little bump in fuel economy too.

Good to know. Now the 64 dollar question - Will it be enough so I can tow 12k lbs without being a dog?
