How long have you been driving in the 400's on stock internals?

I've been pushing it hard finishing the tune for the last 4 months. I was at 380+

Nice to hear. I'm running a gtx2867 pretty hard in the 400s and wondering how long this bottom end it going to last. Any drivetrain issues yet?

None yet (knocks on wood loudly three times)

Tell me about your fueling issue. I had a leaning out problem too that I think was software related.

If you need help feel free to hit me up. I have a screencast on the solution but I haven't posted it yet. I was sick and sounded like shit so I'll probably re-record it first lol. In the mean time I can just walk you through it.

Allegedly, there is a fuel injection limit in the stock software. This for my car meant that after 15 psi, no more fuel volume was injected and the car exponentially leaned out after 6K RPMs.

I am rocking a temporary fix that was creating one more custom map that multiplies injection volume at those problematic RPMs. Not fun fix because the leaning out was not linear but works good enough for now

That's probably not my problem then. I was getting a lean condition going from WOT closed to WOT at high rpm. Like during a quick shift. I was also the guy running 550s pretty hard on corn though. Car has 1000cc Boschs and a hardwired walbro485 waiting for its turn on the dyno now. Hopefully its fixxed.

Could must be the throttle delta comp maps aren't tuned quite right. They're not very good stock, and of course need to be adjusted when you change the injectors (they're expressed in ipw and don't reference the injector scaler)

Pmed to not threadjack.

Full race has this as an option as soon as they can get their kit out onto the streets. I really want to see this tested against the 3076.

Car sounds great, nice video too. Now we need some driving vids at 496whp :-)
