I don't have any what I would call great 3rd gear pulls but here are two and one csv of my 12 second run. Thanks Rob, I really appreciate it!

I would look into the ade or atm intercooler if you didn't pay yet those 2 and the Wagner have always been agreed as top performers in any fmic thread and they should be ok with your stock turbos as well as upgraded.
Just saw this post. I know the Wagner is top quality and I am not sure on the others but it is hard to be the price of the VRSF. As long as it holds out until a Turbo upgrade I will be happy.

It will def be good for turbo upgrade just their big race core is little to big for stock but their reg and hd core would be lacking for upgraded so you did right thing buying for your goals not your current setup.

The good thing is they were clean pulls cause the torque was little off on both probably slight wheel spin at spool but the calculator came back with identical shift points so we know it's good and fairly accurate plus the hp seems pretty accurate cause other dynos read lil higher .I have it set like a heartbreaker and all weights wet with half tank and 200lb driver so not optimistic at all. I figure this way I'll always be happy when I hit real dyno.

I think you are spot on with all the variables. It was about a half tank of fuel, and I weight 200#s :)
I have Virtual Dyno installed but I have no idea who to set it up. Thanks again!!

Np which vd do you have the Brad something one? And on windows? cause I might be able to send you a config for your car like obviously we all have same coefficient of drag and such but I can put your tires in and then if on flat road with good traction it's very accurate. This way you will be able do yourself or just pm me any runs and I'll send right back I can do on my phone so it no big deal

Yes, I am using the Brad Barnhill 1.7.7 version.

For future if want more accurate tell me temp and humidity and tire size. Im using standard m sport bumper for frontal area and bmw published drag coefficient. All 335 bumpers are very close 135 may have different wind resistance specs. Btw the auto I have set for 19s with 275 rear tires so will be a little lower than the mt which I have set for 18s stock size

Interesting. Good info. I suspect the VD is low because of the shit weather i took that log in but damn, our numbers couldnt be more different @NoGuru lol. i know when i took that log it was 3200 DA and 65% humidity. But no worse than his drag pass data.

Nice to know i was pretty much shifting in the right spots.

Car was on E40 tune ots tune, psp 750 intercooler and no secondary cats. All else stock. Tire size 225-45-17 all season run flats.

I would assume that the extra flow is letting the stock turbos make alot of midrange and your trans has closer ratios so makes more sense to not wind out as much. As much as inlets help top end not fall off so bad I guess they help the area under curve even more so that prob explains the diff shift data and also yes that info made big difference
