Not that I was told about. It still pulls to the right and also there is a vibration in the steering wheel when braking at around 60 MPH. I'm not sure if they are related or if the braking vibration is an entirely separate issue.
I ordered the V12's yesterday. I couldn't pass them up even though they are not the best autox tire. They should still work great for my setup. I was also ready to order the Bilstein HD's and Swift Spec-R's but the HD's are out of stock until about August according to GTworx.
I'm also going to start tuning it in the next week or so. We did a pull when I first got it and it read 207 hp via virtual dyno which feels about right. I got EvoScan and EcuFlash but this will be my first time using them. I have previously tuned my DSM myself on SD with ECMlink V3 which is super easy to use. This Evo system looks much more difficult. My car was "tuned" for 20 psi by the previous owner and I'm thinking that is why I am missing a good chunk of power. I have already removed the MBC and hooked up the stock BCS. I am probably going to start with a stock map, rather then trying to figure out what was done to my current one, and work from there. If anyone has any pointers feel free to pass them along. They could be beneficial to the entire STU discussion.

When I installed the v12's my car stopped pulling to the right and now drives straight. Stupid Nankangs I had before. Also for autox the car is much more controllable, although it still slides a little bit. I can deffinetly work with it now.
The steering wheel still vibrates when braking from 60-80 mph. I'm going to get the brakes inspected to see if the rotors are warped.
I'm on the stock tune now but only hitting 16 psi. I tired a friends BCS but it was still only hitting 16. I have the OEM vacuum lines with both "pills" installed and properly routed. I checked the turbo shaft for play but it feels solid. I have boost leak tested to over 20 psi and it holds it just fine. Any ideas as to why it's only hitting 16 psi?
At autox this weekend by car felt a) underpowered and b) very loose and sloppy.
I have a wideband now, along with evoscan and ecuflash, so I will start working on my timing and afr. I will only be able to pick up but so much power being 4 psi low though.
I'm hoping the new Bilstein/swift combo makes it feel more solid. Is it common to feel sloppy and loose on the stock 80k miles suspension?
Here are a few pics and a video from the event on Sunday. I am welcome to any constructive critisim. I'm still a new autoxer. I know I was setting up wrong for that first S turn, hitting the apex way to early ad getting thrown to the outside.

Yes, given how heavy the EVO is on stock suspension it is extremely sloppy (even when new). The car really transforms when you put bigger sway bars and good coilovers.
Want to see something SCCA missed...
Look above at Saturday 8a.m. 2 hardship runs for those unable to make runs Friday... SOO... if weather looks to be better Saturday than Friday...* (wet vs. dry) or you just think the course wil rubber in more.. you can wait and do your runs Saturday a.m., when your competitors who SHOWED UP Friday, had to take theirs.. I have asked SCCA national for clarification of that setup/rule, as it seems competitors are opportunistic, especially with contingency $$ in play... and this needs to be known so each person can strategize.
Cliffnotes: Seems like this concept wasn't fully baked yet...

That is possible. I am planning on looping the lines so it runs wastegate pressure just to see if anything changes. I will also pop the linkage off and make sure the the arm moves as it should.

Sure - we can change the clamps on the unpressurized side -- intake to compressor. But from compressor to intercooler and intercooler to intake.. umm.. My interpretation was that we can't touch anything (meaning no silicon hoses, no metal hoses, and no replacing the clamps)
So .. what rule allows replacing the clamps on the pressurized side?
(And please don't read this as me being confrontational.. I just want to know what rule you're using to interpret this as allowed - so that when someone in my region calls me out I can point them to the allowance.
And then I too can upgrade my crappy oem clamps with some that won't rip up the hoses.)

When I was competing in STU (more than 2 years ago) we got a clarification from the SCCA nationals folks in Kansas about that. The reason being, EVO drivers were popping the intercooler hoses from their manifolds during their runs when using the stock worm clamps (happened a bunch of times). T-bolt clamps, were installed as to improve reliability (there really isn't any gain). There is a lot more to be gained from intakes, headers, full TBE and an ECU tune. I would advise you get clarification from the SCCA in your region if you like. Anyone who protests that is a weenie, IMHO.

Hardware items (nuts, bolts, etc.) may be replaced by similar items of
unrestricted origin. Safety wire, threadlocker compounds, and locking
nuts are permitted. These allowances are strictly to allow components
to be replaced from alternate sources other than the original manufacturer.
They should not be construed as an allowance to replace components
with those which could be considered a ”higher performance”
alternative. Parts available as replacements through the dealers parts
department, the factory, or any other source which do not meet standard
part specifications (e.g., hardness, size, etc.) are non-compliant
in Stock Category, except as specifically provided elsewhere in these
rules.

STOCK CATEGORY 13.10.J.
Silicone replacement hoses are permitted as alternate components
provided they meet the requirements of Section 13.0 with regard to
size, shape, location, and performance equivalence. Replacement
induction system air intake hoses must also match the standard part
in stiffness, contour, and internal wall texture.

IIRC there were some subie dudes that were popping hoses because they were using the ST* creep allowance to create uncontrolled boost spikes. If they swapped to t-clamps would that be legal? It only helps them with reliability.. it doesn't *make* the power..
I'd argue that a clamp that keeps the pipe connected is a "higher performance" version of the clamp.. I wonder what the STAC would say. I'll ask! (If someone has already asked .. can you point me to the fastrack date?)
