Hesitation in boost and high rpm

[BoostedSho2010]

I have been driving the car on the stock tune for the second day and it feels healthier. Throughout the RPM band its obviously slower but it has like a harmony to it, I can feel there is no monkey business going on with it even though from the logs, you can see its heavily closing the throttle.

There was also sometimes a drop in rpm on the LMS tune when i would be coming to a complete stop which would cause a bit of a vibration (rpm dropped) and the rpm would then jump a bit past idle and calm down to a regular steady idle. I can't reproduce that on the stock tune.

Mine does that goofy idle drop as well.

Mine used too until I had my strategy updated... no longer does it do that.

Mind if I ask what strategy you have now, and how/what did you tell the Dealer to get them to do the update for you? 
I am on KHDK4, and one tuner had mentioned it might be nice to make sure I am on the latest strategy.  When I asked the dealer they pushed back saying no reason to do it.

I know mine idles low and bounces around a bit at idle.

The original strategy for my 2010 SHO was DMJK1AB and then after several updates it is now at DMJKBLA. Livernois had to "build" a new tune for my strategy since I was the first one with that strategy to get a tune.

The first dealer I went too flat out refused to perform a strategy update. The dealership a bit further down the road didn't even question, they were more than happy to take my $100....

Hey Guys,
Got back from my trip. Gave LMS a shout and got some crummy news. No one over there has touched my issue. No update or course of action.

Edit: Left Andy a VM I'm sure he knows more but it takes 48 hours to hear from him.

[SHOdded]

well, time to pursue the issue   I am sure they have a million things distracting them, so they need to be poked regularly!

[polskifacet]

Waiting on Andy to call me back should be today honoring his 48 hour call return policy. Also left Anthony an voicemail, figured I give Ethan a break, I'm sure he hates me by now lol.

SCT had never even heard of this STRATEGY before I called them and send them pics of the SCT tuner .. I am currently running DMJKBLA .. the previous OEM firmware was spastic as hell.   if i put my foot on the gas in park.. just a tiny bit it would idle up to 1000rpm .. then choke itself out.. drop under 400,  sputter, recover... then do it all over again about every 50-60 seconds on the nose.

AJP had me update prior to tuning and it no longer does that ..

SCT is full of crap... I have the same strategy..... and have called them for support...

I know man but I have done everything that LMS has suggested and see no clear sign of anything being wrong. Anything failing would continue to fail, get worse and I would see a change. It is completely static.

I'm thinking about putting in an aftermarket fuel line but would need community support on the correct fittings and retrofitting the fuel pressure sensor near the tank.

Hmpf I have not had satisfactory interactions with SCT until I talked to Kevin.. he's the one who put my dmr ticket in.  Everyone else has not been confidence inspiring..

Dang all that quoting makes it hard to read on a mobile device LOL

No kidding.  I need to get taptotalk installed.. but it freaks me out put my creds

[polskifacet]

Another day with no info from LMS. I'm confused why they don't want to simply try and change the values AJP suggested so we can all be done with this. Maybe all of you guys need to start calling LMS and asking what the status is lol.

Welcome back Adam!. How was your vacation?
I will try to contact them for ya but remember there are so many variables to consider in this situation. Z

It has come down to tuning around my issue. I wish they could just do it as what has to be done has been stated by Brad. If LMS doesn't have confidence that they can find the issue with my car in a timely manner, what choice do I have?
