    0-60 times off on 2011 SHO

    Unleashed uses the SCT tuner, which makes a copy of the "stock" tune on the car now. However, my understanding, LMS just uses a canned stock tune (for the particular strategy) already loaded on the tuner for the buyer. The tuner doesn't need to copy the stock tune that's in the car before...

    Ptu unit and possible trans going out

    If yours is good to go now, don't mess with success ;) Sent from my iPhone using Tapatalk

    Ptu unit and possible trans going out

    I guess "overfill" isn't clear. I was told one pint over, but I'm not sure if that means over the "hash lines" full mark or over the "max safe line" full mark. Sent from my iPhone using Tapatalk

    And did you "overfill" the trans a little, per LMS recommendations? If so, by how much? Sent from my iPhone using Tapatalk

    My gut tells me it is more likely the adaptive learning lightened his shifts over that 3 week period. No offense, and I acknowledge I might be wrong ... Sent from my iPhone using Tapatalk

    Ptu unit and possible trans going out

    Personally, I have had no luck. I love my LMS tune, but I have tried softer and softer shift tunes from them - even going down to stock shift pressures. But, it still gets about a 1/2 second shudder on 1-2 at WOT. AT first, LMS advised to let it learn, but that hasn't done much for mine. They...

    The 1-2 shudder at WOT is common in tuned vehicles. Most have been able to eliminate or mitigate it with a tune revision. Sent from my iPhone using Tapatalk

    Sludge in the Intercooler!! Could this really cause lurching and other seemingly transmission woes?

    Fair enough. Hope you're right Sent from my iPhone using Tapatalk

    Sludge in the Intercooler!! Could this really cause lurching and other seemingly transmission woes?

    Problem with this theory -if the sludge was that thick, it was unlikely to have been sucked into the intake. So, how would it have affected performance? As much question as statement ... Sent from my iPhone using Tapatalk

    Transmission - normal operation?

    OP, this is normal. The car is programmed to engine brake, as it is assuming you don't want it to accelerate down the hill with your foot off the gas. I drive highway hills everyday, and mine does the same thing -- much more aggressively with the cruise on (trying to hold the cruise set speed).

    Took car to dealer, couldn't find anything wrong!

    As for the sound you recently heard, if I goose the gas in 1st and immediately let off, I sometimes here a whistling or whining down sound if I listen closely. I chalked it up the the turbos spooling back down. I figured it might be worse with my car tuned given the increased boost. Then I...

    Colder spark plugs with a stock tune?

    Good info, as always. Thanks to you and shoblock Sent from my iPhone using Tapatalk

    Colder spark plugs with a stock tune?

    Interesting. I am going to put new plugs in now. Sounds like sp534s with a .030 gap will be good with both the stock tune and LIKELY the aftermarket tune. Sent from my iPhone using Tapatalk

    Colder spark plugs with a stock tune?

    Sorry to keep pestering, but aren't gaps for both .030? I know the owners manual calls for .030 - .033 ... Sent from my iPhone using Tapatalk

    Colder spark plugs with a stock tune?

    So I'm reading that I can put new 534s in and know they'll likely be fine for a later tune (3 bar MAP and possibly thermostat as only other mods). That about right? Sent from my iPhone using Tapatalk

    Colder spark plugs with a stock tune?

    Are the 534s generally accepted for tuned vehicles, i.e. Do most folks feel it not absolutely necessary to change out to 6510s? Sent from my iPhone using Tapatalk

    Thanks. Torrie at Unleashed tells me that the colder plugs are a good idea with tune, but I would certainly be open to other opinions ... Sent from my iPhone using Tapatalk
