I've taken mp4s and indy 500s down in the mid 20s without issues. I wouldnt go hooning until they are warm but regular commuting in traffic is easy. Half way through my commute they are hot enough to mess around.
The stock fuel pump can handle a bap surprisingly well. My pump had about 105k miles on it. Ran a vms bap since 48k miles. Only swapped it out then because I got a great price on a dw400.
Yes it made you paranoid lol. I did my first around 5k and everyone after that around 5k until I boosted it around 48k miles. Swapped to 4k intervals. Engine ran strong up to 96k miles when I botched a spark plug change and trashed cylinder 3. Went 4k on the new engine in between changes again...
You can probably get away with one or the other at that power level but the dw pump was designed to run at 18v. For a couple hundred extra bucks that's good insurance you'll always have plenty of fuel.
If its on the drivers side I wouldn't rule it out. I've always had minor exhaust leaks around my vband clamps but never got a lean code until this year.
Any chance you have an exhaust leak by the o2s on your drivers side? I was getting an intermittent lean bank 2 code for a while and it was a leak at the vband right by my upstream o2.
Press the brake way harder than you think is necessary. If the bar is starting to move but never goes all the way up you arent pressing it hard enough.
If it doesn't happen again you're probably fine. If it continues to happen look at the hydraulic system. My gt did it once a few years back while driving. I lifted the clutch pedal with my foot and it went right back to normal and never happened again.
I've run meth for the last 4 years or so. I just use it for the extra protection since we have crappy 91 out here though. Not tuned for it. Just a safety net.
Most good transmission shops i know will tell you not to flush the transmission. Just drain and refill. Flushing can cause metal shavings to recirculate through the trans and cause premature failure. I don't know how much truth there is in this but it makes sense, especially a transmission...
I had 95k miles on my stock opgs when I pulled my engine and they still looked brand new. I regularly wrapped it out to 8k and caught the limiter more than I'd like to admit. I wouldnt be doing opgs on a gen 3 unless you are planning to abuse it.
