I went over to Alternative Auto today for Lidio's Fall Dyno Day ($50 for two pulls). I have been running the email tune that comes with the Xcharger and haven't had a chance to turn it over to Lidio yet for a custom tune - although that will probably not happen until the intercooler comes out for the Xcharger later this year. Looking at the data, there is a lot left on the table with the base tune - very rich AFR (10.0 at WOT) and it was still pulling hard when Lidio got to the rev limiter.
Saw this and everyone was crowded around saying "look at the torque that thing is putting down!" But if you look closely you can see that the tach signal was messed up. Lidio tried a second pull and thought he had the tach signal fixed.
So he made some more adjustments and said "let's do another pull, I think the tach signal is reading correctly now"
I know that there is a lot more we can get out of it, it is tuned to be very safe right now. We talked about some tweaks and will be getting it back in for a session to tune it up sometime this year.

Best pass so far on the X is a 13.8 - still trying to figure out how to launch with the boost. On nitrous of course it was a N/A launch and then the nitrous would come on (netting me a 13.6 on the juice), but the Xcharger builds boost so quick that I am into a couple of pounds just trying to bring the RPM's up.
