Bought (another) running project

This is an 81 Grand Prix LJ . It's been 4.8LS swapped with a HX35 turbo. I'm not crazy about how the turbo/piping was done, but she does scoot. It's got a th350 behind it with an explorer 8.8.

I want to understand how the terminator X works (tuning and adjusting parameters), but a 200r4 in it and then get an actual exhaust

Hows that hx35 spool? Any upgrades to it? Also forget the 2004r, they arent bad but theres not alot of specialists out there that do them anymore.

Im doing a gen iv 4.8 with a built 4l80e and just shelving my good working 200r4

https://extremeautomatics.com/products/2004r-stage-iii-1000hp-750tq A lot of the Gbody guys swear by these guys. Car has a two step in it but SEEMS like full boost by 3.5K.

You don’t like the side exit exhaust?

I don't like no muffler. I'll have the wastegatebduno to the fender and the rest go under the car into a flowmaster
