200tw for sure. I'm a fan of continental ExtremeContact Force for consistency and longevity. the only downside is they won't be great at autox, because they take some time to heat up. if you are more focused on autox then maybe try the new bridgestone re71rz. the hoosier track attack pro would...

What a lot of these don't account for is transient response. I'd argue the difference would be more noticeable if you downshifted and floored it at 5k vs. doing a full 2000-7000rpm pull

technically they're all bench unlocks. only difference with femto is it's on femto's bench using their proprietary tools.

do you mean the evap tube? do you have a pic of where the leak is?

this is part of the cause. the explanation from BMWs is that sometimes the car will struggle to start, presumably from a worn/old starter, but the starter will keep cranking for an extended period of time. originally there was just a software update to prevent the excessive cranking, but they...

for the record, there's a B58 one too. the only difference is they haven't confirmed the recall because there's no official fix. but they acknowledged that there is still an issue with the starters failing and potentially causing a fire.

still waiting for this to come to life

you're not capped to any ethanol percentage. the flexfuel tune can run any amount of ethanol on stock fuel system, so you can run full e85 if you want. the best performance will be at E40, but the tune safely dials back boost for higher ethanol mixes or full e85. OTS maps are designed for the...

i'm saying that this is the case for multiple companies during this season because they preorder inventory in preparation and they cannot stock it waiting for more order next year, so sales are final. that has been my experience.

to be fair, it's because of black friday. last I saw, they got a ridiculous amount of orders during the "power hour" sale alone. so they preordered a bunch of inventory but they have to work through all the orders. everybody's in backorder during this time every year.

thanks for the tag. OP, just one thing I recommend I did for peace of mind, is spray some lubricant in the joint and cycle it in the wastegate a few times before install to spread it around. helps keep anything from getting in there and keeps it moving smoothly. no, it shouldn't be necessary...

are people having this issue with stock hpfp?

yeah, that's why i tell people just don't put tpms in your track setup. just deal with the light and send it. no need to worry about coding out tpms etc.

the people i know with the spool kit definitely comment on the delayed spool and peaky response up top. It's "fine" but far from ideal. For the power it shouldn't be that laggy. Times won't reflect everything related to daily driving.

TPMS showing low pressure = limited drive modes No TPMS = no restrictions

seems less and less likely. they use the mild hybrid system to make a power bump on some cars, but that seems to be it.

pure900 isn't stronger. it just flows more air. that means more power at the same boost pressure. the benefit on 93 octane is that octane limits come quick when a turbo is superheating air. on a bigger turbo, you can make the same power on less boost, which means less heat, which means more...

Like i said, i worked in OEM manufacturing. Some of us aren't just guessing here. We have hands on experience. You can't believe that the industry targets such lofty quality metrics. Meanwhile, my engineers can't believe we hit our process capability requirements and we still get warranty...

you've got double my time in which means you likely have half as much hair. godspeed.
