I agree your setup should be around 400 rwhp on a dynojet, but not running that AFR. Bump the rev limiter to 6600 rpm, tune peak torque to 12.5 and anything above 5000 rpm lean out to 12.8. LS6 intake, bolt ons, unmilled 243s and a small cam is right around 400 rwhp. Mill your heads a little, do a nice valve job and throw on a ported fast like my setup and it will really rip. Also 243's like 22-24 degrees of timing up to 5000 rpm and 23-25 degrees up to the rev limiter.

Hey Bene: My 2cents
Tuning issues aside, you already said in another thread that you could really feel this cam pull.
When I install my eps 222/226 113 I'll have your same setup but on stock 241s. Geoff told me I could expect around 380rwhp give or take (just for reference, I'm not holding him to that number)
From watching your clip, it seems to me the issue is reconciling 1) the dyno numbers with what you would see on a dyno back in the US, and 2) the inconsistency in back to back runs 440-480-360...??? Clutch?

Remember this is a loaded dyno, dyno dynamics, famous to spit out lower numbers than any other dyno already.

I'm going to try to convince him to see to run the car just once on 4th gear just to see the numbers when I get it retune.

Go register on www.hptuners.com and start reading / posting. If you want you can post up your tune and I will look it over to see what needs to be adjusted.

he chose to do it on 3rd because of the fact that he didn't want to run the car 100+ on the dyno.
I guess the Brits are so polite they take responsibility for it?

I know this thread is a little old, but I just stumbled across it and felt compelled to post as I'm sure the OP will be interested in what I've got to say.
I'm in the UK too and had my Z28 dyno tuned at the same place as the OP a couple of months back after having my LT's fitted. It made 369.4 rwhp, which was calculated to be 450.1 hp at the flywheel and there's no way my car should be making as much power as the OP's, so something is definitely not right...no idea what, but somewhere something is not right. My graphs are below...
