Late to the party, but I would recommend the 3500 LC option to use 3.5K/3.25K/3K. 4K is just too much for this car with the ECU tunes. 3K is probably optimal without drag slicks, but with the 3500 option, you can bump it up a little. There is no reason to be locked at only 3K, so go with 3500 option to have 3 additional choices without going nuts and catching rubber on fire.
Ah - just a tad late as I got it tuned this morn and went with the 4/3.5/3 option!
And having just done two quick dragy runs on my way home, I'd say you were probably on the money as I notice that 4k launch does light them up. Still, got to work with what I've got for now....this is one of those times where I'd say wouldn't a flash from home option be nice
So first impressions on the v2 APR Plus tune - I like it. As others have commented, in general driving it does seem much smoother and refined than the older version. I'm guessing a lot of this has to do with the revised throttle mapping - it now does not 'surge' like it used to sometimes in part throttle situations. It really now does have a very OEM+ feel about it. Not that the old tune was bad, but there is a distinct difference.
A very good thing I noticed is that the in dash boost gauge is now fixed as Arin had said. Before, it would cap out at 36.2, so you never really knew how much you were boosting. I have now seen that figure jump to 40.3 or so, so subtract my sea level 14.7 and it seems peak boost (here on an 88 degree warm day in Florida) is between 25-26 psi.
Butt Dyno said power is still all here as it was before, although you have to push a bit further on the throttle now due to the revised mapping, but my foot will recalibrate. It's better, as before I think you were probably getting 100 percent throttle at 3/4s pressed down.
The two dragy runs I did however say it's lost a little.....although I will hold judgement on that for a couple of reasons, first being that they were fairly hasty and not on my normal deserted roads I drive to, second that I think I need to play some more with launches etc and third, my last good runs were in February when it was a bit cooler.
Best 0-60 I managed today was 5.80 (previous I had managed a 5.43 and 5.6 regularly). Best quarter mile today was 14.05 at 101.5ish (previously I'd done a 13.7 at 104. Half mile today was 22.5 at 120, previous best was 21.5 at 124.5.
As mentioned, I'm not done with it yet so won't call those figures final, although to be honest I was expecting a drop vs the other way round based on a couple of horsepower less and 15ft lb of torque less on the new tune.
All times done on 93 gas. I will he interested to see how it does on the 87 it is now tuned for (previous version was tuned for 91). Once I get happy as can be with a few more 93 runs (maybe during the morning when it's cooler), I will run that tank down and fill up with 87.
But all in all, times aside - the car feels nicer to drive without any unpredictability. Again, not that the old tune was bad, but it did feel more 'tuny' if that makes sense, whereas this is now more refined.
