When i was doing alot of reading for my car I came across something online that may help your tuning. I think your MS has a map sensor built into the box correct? So this means that you have to run a vacuum line from the engine to the MS ecu? People were saying regarding tuning like that witht he supras that it is better if you either plum a hard line for most of the run from the intake to the ecu or have the map sensor as close to the intake as possible. Can you run an external map sensor and input it into MS to work the same as the internal one?

Not sure. But I have no desire to run an external MAP sensor to be honest. It means I have to drill/tap a sensor into the intake, then run all the wires for that. I personally love the idea that I do not have to do that, and simply just need to run a vacuum line to the box.

FYI my setup actually has 2 MAP sensors, 1 which is hooked to the intake via a vacuum line, and the other just open to the atmosphere, that way it can correct for barometric differences, which is pretty sweet I think.

Hit the dyno today, went much better this time around. Dyno video with results will be posted in the next day or so :P Here's some teaser pics:

So where are the graphs!?

Alright so here's a rundown of the dyno.

To start from the beginning, I dyno'd a week ago. Got all the cruising type tuning done, car is running and starting great. But couldn't do any WOT tuning because of what turned out to be a bad coil. With the coil replaced, I returned to the dyno yesterday for the WOT tuning.

You'll see the first run was at about 339hp. Shane did his thing, 2nd run we were already up nearly 50hp. A handful of more pulls and we stopped it at 406hp which far exceeded my expectations (I was thinking more like 360). This is on straight WG boost, no boost controller. You can see how soft boost comes on with this WG. I thought it was a 1bar spring but maybe it's more like a 10lb. Will have to look into swapping that out this winter.

I can't thank Shane enough, I'm very happy with the entire experience (as always). One thing you'll notice is a random blip in the curve at around 3500rpm. It would occasionally miss at that spot very slightly. Not exactly sure why but not that worried about it either.

So I've attached the 3 charts (HP vs. Boost vs. TQ vs. AFR). Creeps up to about 12psi at the end.

Also attached is a little video. Thanks to Kerry for taking some good footage at the dyno, enjoy!!
