I have to figure out where to get a water temp from and I guess I need a replacement Aluminum transmission pan so I can drill and tap it for the Trans Temp Gauge.
I only pull 8 to 9 inches of Hg Vac I am guessing this is because the car is an Automatic Transmission. My manual MINI and Ford Focus ST both will pull 24 to 25 inches of Mercury on decell if engine braking. Is this normal?
The stock pulley (3.5") makes about 5 lbs of boost with light throttle and peak at ~14#s with it matted on the highway for a quick second, I was a little shocked, I did not even install the smaller pulley yet, what is that going to make?
Still need to:
Install the NOS cooler for the Air to Water
Hook up the 2 other gauges (water temp and trans temp)
Get car tuned
Go to track

I have a 2010 automatic, with a small Roush M90 blower (1.48 L). Same 4.6 L eng.
Boost goes from 4.6 psi... up to 5.8 psi (750 rpm to 6200 rpm). 482/ 470 crank hp / tq.... and 387 / 372 rwhp / rwtq. This is with 7 bar upper grille, K+N air filter, FRPP twin 62mm TB, and JBA ceramic LT's and hi-flo catted H. Also a VMP 94 (no ethanol) octane tune.
-10 inches HG while cruising. -20 inches HG on de-acceleration. IF I manually shift to 3rd gear on the 5r55s, it will pull -22 inches G on de-acceleration. -10 inches HG at idle.
With an aeroforce gauge plugged into OBD port, I can easily read the auto tranny temp, plus a ton of other 5r55s auto tranny parameters. No need to drill out pans etc. Aeroforce gauges mount to a SOS A pillar. Roush boost gauge mounts into extreme left air vent.
It appears with your 5-14 psi boost on the oem big pulley (should be 5-8 psi per edelbrock) and your 8-9 inches of HG (on de-acceleration?) something is amiss. It's like your boost / vac gauge is reading 6 psi too high.
The 5r55s is not a HD tranny. Per edlebrock, they don't alter anything in their tune for the tranny. With the blower on, the shifts have to be firmer and faster.... or the poor 5r55s won't last very long. VMP fixes all of that, and also allows the user to tweak parameters on the SCT X3 / X4... like shift firmness..and also rpm / speed ...shift points on a shift by shift basis. 1-2, 2-3, 3-4, 4-5.
Once 5r55s is up to temp, it sits at 170 F. Mine would increase from 170-200 F.... in just 5-8 secs with blower on, gas mashed, on the hwy..+ it would also puke ATF. My fix was a JDM engineering catch can for the 5r55s. PA deeper pan was used, 2.1" deeper ( made from 5/8" thick aluminum.. with rows of thick fins). Deeper pan holds an extra 4 qts of ATF. Pan comes with a magnetic drain plug. Also comes with a locking style dipstick, big enough to allow adding ATF, if required. PA pan weighs 10.3 lbs.... vs 3.2 lbs for oem steel pan. Also switched to RP 'max atf' 100% synthetic atf. Also installed a B+M auto tranny cooler ( 3/4" thick, 13K BTU, bar + plate style, cheap from summit / jegs etc)....in series with oem Ford tranny cooler.
Ok, now the tranny temps only increase to 171-172 F.... doing the same 5-8 sec hwy 'blower on' test.
The oem 5r55s is the weak link in the chain. You want to avoid 5-3 shifts, 5-2 shifts, 4-2 shifts. Drag racing is fine, with it's 1-2-3-4 upshifts.
