  1. MHD no lift shifting (NLS)

    I’ve only seen a couple people mention their experience with MHD NLS and it seems like the majority have lost more boost using it than shifting normally. What is everyones experience with it?
  2. Official NC Owners Thread

    @raleigh.car.events on Instagram posts weekly with all the meets going on in the area. As far as parts, good ole Facebook marketplace is your best bet
  3. Custom Tune

    I mean it's not going to really reflect having a tank full of 93 because of the existing e in the tank
  4. Custom Tune

    If they already blended for e30 and then were doing a 93 tune, wouldn't that 93 tune be somewhat obscured? I can't imagine they would've fully burned off that e30 and that just seems like it'd be a backwards approach
  5. SUPRA ULTIMATE B58 JB4 GUIDE AND LOG REVIEW (V1)

    I can't remember what the default biases are but definitely lower the boost failsafe to 22 until you start adapting the tune to your car and get logs to make sure everything looks healthy
  6. Custom Tune

    I see you're also in NC so what shop was this? Did they also tune it on pump gas/lower e blends? The only thing I could think of is if they just put enough e in it to get to e30 and then diluted with 93, but I don't see why they would

    Trans reliability at higher torque levels isn't relevant when we're talking about the trans?
  8. Haha! C'mon man!

    MT trans holding up to 700+ torque on several cars. How's the auto hold up at that power?
  9. BIG News! The Active Autowerke Catted Downpipes Got Even Better!

    That's going to be an issue with the dp or o2 sensor. Unrelated to having the jb4 unless you're running ethanol or bad fuel and it's related to the tune not running well
  10. BIG News! The Active Autowerke Catted Downpipes Got Even Better!

    Yes, but jb4 did not cause the code. You are just reading the code using jb4. Unless it was caused by a bad tune on the jb4
  11. BIG News! The Active Autowerke Catted Downpipes Got Even Better!

    I had a couple of these lately while doing a custom e20 tune, but it was due to my trims being too high which caused it to go into limp. This specific code only came up 2 out of 5 or 6 times it went into limp though. What were you doing when this popped up?
  12. BIG News! The Active Autowerke Catted Downpipes Got Even Better!

    Codes are based on the ecu and sensors, so no, jb4 wouldn't cause any codes that you wouldn't have gotten otherwise

  14. SUPRA ULTIMATE B58 JB4 GUIDE AND LOG REVIEW (V1)

    Is the variance in e content from pump e85 enough to warrant any concern?

    It’s kind of odd we can’t delete our own threads lol
  16. SUPRA ULTIMATE B58 JB4 GUIDE AND LOG REVIEW (V1)

    How safe/consistent is blending ethanol yourself for map 2 & 4 without using a flex fuel kit? I plan to go PI/visconti reflex in the near future but I would like to run some ethanol in the interim with the jb4 I already have. I don’t think a flex fuel kit would be worth it since at a minimum I’d...

  18. Heated the trunk a bit too much.

    Paint fades from things like sunlight exposure. If anything, the paint under the spoiler will look newer than the rest of the paint

    Right, but it still blows stock turbos. Get a custom tune before you start running e on map3 also map4 is e30 with absolute target of 20 instead of map 3’s additive 6lbs
