ok my idiT swap is pretty much done...cpl problems i am having....the abs light stays on all the time...there is a gold color box under the dash....i unplugged it and the light went off, is the abs the only thing this box controlls, everything else seems to function fine...i am putting a pic of it up...not a good one...and there is a little vacuum controller that is a mystery on the passenger side fenderwell. ithere is a pic of it too...can anyone tell me anything about either of these 2 items

 

ok what is this

 

Its a vaccum manifold....

 

vacuum manifold to what? here is a crappy pic of the item under the dash that i unplugged

 

That looks like the low vacuum switch.
It should light up the brake warning light on the dash if the vacuum pump fails, or there is a big vacuum leak.

The vacuum manifold is usually mounted on the firewall close to the heater box, though it may have been moved for the factory turbo trucks

 

out with the old
in with the new
after a slight modification to the down pipe, i cut the sides out that were pinched down and welded 1/8 plate over it

 

The little gold box appears to me to be the voltage regulator for the dash guages.

No doubt your DP mod helps, but why not go 3" since its already out?

 

It was free for me to modify the stock DP....i got my rebuilt turbo and glowshift 3in1 egt.boost,temp gauge in today too...so this weekend is tuning weekend right after a new rear main seal

 

might as well do the 3" exhaust elbow and DP upgrade..... no reason not to, this is the perfect time.

 

Lol....money is tapped out

 

Speaking of which, Justin. What does a 3" v-band flange and clamp cost? Thinking of re-doing my DP flange... it be leaking. Dunno if the 3/8" warped or if the "gasket" is bad, put pours out of the bottom of it where the WG is.

 

Well after my turbo and gauge I was disappointed to see only 5 lbs of boost....i need to work on that...it sucks

 

was that under hard,full load?
cus that's about what i see just running empty on small grades.i don't peak 9.5-10ish until im loaded up going up a good hill with some rpms.that or running up a mountain empty,that'll do it too.
so just be careful.that boost gauge changes real quick when you hook up to something or climb a real hill.
set 'er up so you hit 10 lbs easy when empty,then your EGT's can get quickly out of hand when working the truck (if you do) without an intercooler anyway.

 

I would suspect a leak somewhere, granted i have a different turbo, but even wastegated i can hit 15 empty on level ground in 3rd.

 

I hit 11 in my non-wastegated ATS 088 turbo....that was without a fuel adjustment.
