Cosworth probably made the biggest difference, considering we were running approx the same boost levels (6.8 on mine, 6.5 on his) I've got the MD spacer and MREV 2, and mine is a revup, whereas his is not.
23 rwhp for the Cosworth is nice! Plus it's all shiny and carbon fibered!

Each tuner will have their own [reasonable] preference though.

So, yeah, it seems high, and it might very well be high, but there's some sort of method behind it.

For what it's worth Robert, I had a tune on the Dyno-Jet then the Dyna-Pack I think I had like 11 hp difference. Conditions were similar. The corrected thing never goes over well with people that dont live over a mile high, I sort of understand, however it's where we live. Wait til you hit Texas and hit up another dyno...
Congrats!

12:1 is begging for serious issues on a stock block.
On my built engine, I am running 11.7:1 - 11.9:1.

Yes, I am totally confused? I think a fair warning was given, most people who didn't know that 12:1 was WAY to lean for a stock block would probably appreciate this knowledge, before it was too late.
Also, 487 corrected whp, isn't right, it is just wrong even if you were on top of Mount Everest, it's still wrong with the altitude correction! 398 whp is probably about right on. Enjoy your ride, while you can.
