What all will I need to do to do this 112 to 1900. I know a re-tune. I am making 10pounds of boost now. Think there will be much improvement or not pulling. 02 SWB 5.3 headers true Dulles on cats 3.43 gears and a 4L80e.

Thanks Tim

 

I don't think it'd be worth the cost of a swap. 10 lbs of boost is pretty sustantial and the 112's bring it on quick and strong. I wouldn't bother unless I went to a bigger engine.

 

I remember reading on here, maybe from EVILGMC, that when he switched from 112 to TVS 1900, (all else the same), he picked up 30rwhp. But obviously you have more upward potential, but at lower boost levels, probably not worth the extra $$$.

 

That is what I needed to hear. Thanks a lot. May pic the 1900 up for my 1982 truck going to put a 6.0 in it.

 

I did the swap. Cost was offset by the sale of my 112 so not too much out of pocket. The 112 pulls it's own but the TVS is much more efficient, less heat and quieter. The 112 falls off up top, at a point. The TVS never falls off, or so it seems with all the graphs I've looked at.

 

Your sig pic says you still have a 112

 

Fixed it!

 

Lol!

 

Freaking awesome!

 

Haha. Bill, You get a Roush?
