Nice job on the numbers! If you're getting headers, are you also getting a mid pipe and exhaust? The loosing weight thing, if its true remember that 70% is dietand what you actually put into your body. Then exercise!!!! Cut out sugar. Just my .02 since fitness is my thing.

I haven’t decided on a mid-pipe or exhaust yet... I’m planning on waiting to see what my car sounds like with just the PPE Headers. I’m wanting to keep my exhaust noise low!!

Hayarms I think on the top of the dyno sheet it says what type of dyno they ran it on. YOU WERE RIGHT THE CAR IS TOTALY DIFFERENT WITH ONLY 40HP... I’m hoping with the pulley install ill gain another 25HP and then with the PPE headers hopefully another 15HP!! Then after this is all done its time to put the IS on a diet!! IM SHOOTING FOR 200 POUNDS OFF!! 
200lbs off...Hmm. My racing seats cut out about 65lbs, my spare gone is another what 10-20lbs? Back seat doesnt weight much at all, its just cushions. Light weight wheels/rotors?

I'm a gym rat too though

LOL self improvement is def. key! You guys are funny
Honestly, aside from the standard items to pull from your car rotating mass will make the biggest difference! Imagine dropping 5-10lbs per corner just from 2 piece rotors and lighter forged wheels. Those are the best mods I've ever done to any car...though they come with a price but what doesn't?

Right now im lookin at a battery change, both front seats, RB Brake two piece front rotors (need to get a two piece rear made??) and remove sun roof. I never use the sun roof dont care for them. I have already dropped about 67 pounds off my car from a decent wheel/tire combo also leaving the spare jack at home.

Wow, this is SPARTAAAA.
Definitely forged lightweight wheels will increase acceleration and braking performance even further.
I can't wait to see the 1/4 mile time and track time record on Nurburgring haha. Have anyone tried the Nurburgring track with an IS and what should be the time for a stock IS250, a stock IS350, and IS350 with suspension mode, and IS350 with suspension mode and superchager.??

Update on S/C I’m getting a CEL for Bank 1 lean came on twice today while car was at idle.. I’ve had a surging idle since the S/C was installed figured maybe the ECU needed time to get use to the extra volume of air...but I’m thinking I have a vacuum leak.. I’m thinking the synapse blow off valve is leaking at idle causing the surging messing up timing and causing a CEL for lean. Tial Blow off valve will be my next purchase after I check all the clamps

PS: it should stay slightly open at idle/vacuum

You may want to search Synapse here and see how we ended up running that bov. I believe I pulled the spring and used either the upper OR lower port only (I think lower). The valve will work perfectly for your setup if you get it set up right.

How did you run the vacumm line to the maifold I used the orignal nipple that was already there from the factory (the one thats near the throttle body) and plugged my line in their. I was told it worked better to tap your own nipple into the maifold to get better performance of the synapse Blow off valve. WHATS YOUR POINT OF VIEW???

Use either the stock capped barb on the IM or tap your own just after the TB. You should be fine there.
Do NOT T your bov(s) off of the vacuum press/evap near the TB/intake manifold. This caused erratic behavior when I did this as well as a few guys overseas in the early boosting days.

Cars running good now like stock idles perfect! Loving the boost average gas millage I'd now 12.5 MPG. Now I'm waiting on my PPE headers and procharger pulley to arrive. Hoping with more boost and headers I can put atleast 345 to the wheels...
