No- it seems to be running well. I've put probably 1500 miles on it since getting it going with one weekend being 700+... Its got quite a bit more pickup than it had before...
Using a car timer app on my phone (so who knows how accurate, but probably not very), it seems my 0-60 dropped from about 14.2 down to a little under 12. Eighth mile seems to have dropped from about 12.9 to about 10.9....
I've got an appt this coming Wednesday with a tuning shop who does a bunch of Sniper/Megasquirt/etc stuff, so I'm hoping they will be able to help optimize it. Sounds like he usually does street tuning first where I drive and he plays on the laptop in the passenger seat, and then if desired he has a dyno back at the shop we can load it on too if I want to find the RWHP number... Says he likes the street tuning portion better than just trying to do on dyno because it is more indicative of real life driving. I'm hoping for some more positive results after this visit on Wednesday.
Mine is sure grip 8.75 with 3.23:1 gearing... maybe more likely to break free if it had single track.... I know burnout ability isn't a real measure of performance, but do hope to eventually at least be able to smoke them a little bit.
