My 07 LSJ Dyno, M62 309whp
Past 7K RPMs, the car was going way too lean on the dyno (12.4+ AFR) and losing power as you can see on the graph...so we shut it down at 7400. Need to add about 5% more fuel past 7k, peak HP may be a tad higher. Didn't have a chance to update the tune.
Nice work! That is basically the exact same setup I have on my 2nd car, besides I have the stock catback...dat quiet lol. Go look in the war stories section, I think I have most of the posts in the past 2 weeks in there from me racing everyone in my little M62 car
