Not as fast as I can make it feel on the road. I still have a few tests I'd like to do, like start in second gear and/or skip gears to bring revs into earlier in the torque range.
I think the last run on the rollers (without the tuning box) shows where I can tweak things. I might be able to hold on till 4500rpm where power doesnt drop below what it is @ 3000rpm, but that would mean when changing up a gear it'll I'll have the same problem (and also torque up till then does drop off quite a bit because of boost holding back to 15psi rather than 18psi a few hundred revs earlier). So maybe holding 2nd till 4500rpm then changing to 4th would drop me back to 3k-ish in the right area. Tricky business drag racing a diesel . Of course this graph might be different now with the intercooler upgrade and cold air feed.
