First I want to thank David, Nick and Jarrod for working with me on this new setup. Shipping was timely considering the extent of work that needed to be done and everything arrived safely without a hitch.

Here's my current Mod list so you can follow along:
BR HTA 35R 5 bolt .63 @ 30psi on 93 octane ~500awhp DLL prior to the new mods
PTE 1000cc injectors
BR 2.0L
BR Stage 3 head
BR BF272 cams
BR twin walbro fuel pumps
BR 3" tbe, test pipe, bullet muffler
BR 3" intake pipe + Mas adapter
BR UICP
BR Mini Battery
BR Race FMIC
ARP head studs
PPI ported stock intake manifold
PPI 65MM throttle body
Tilton Twin Disc Carbon clutch
Stock ECU/MAS
My tuning www.mellontuning.com

on the way:
BR COP
BR .82 to replace the .63

I JUST got it running last night and here are my initial impressions:

1. It's idling at 1200 with some nice lope, with the HKS 280's at 1200 you can barely tell it has a cam. These are definitely more aggressive. Sounds similar to a GSC S2. I'll get some video when I have more time maybe this weekend.

2. The tone is slightly different when doing part throttle, it has a meaner sound and there's a very slight vibration reminding you that you're driving a beast.

3. Idle with the AC is very poor, I need to work on that it's wanting to stall constantly and I know the super light weight tilton carbon/carbon clutch is amplifying the problem.

4. I did a single WOT pull last night and the AFR looked about the same up to 5500rpm but by 6000rpm the AFR went to 12.3 but didn't knock a single bit. Previously it would have knocked tremendously like that. I added 4 fuel from 6000 on up and it's still in the low 12's and IDC's are 86% with the BR twin fuel pumps and PTE 100cc injectors. I added 4 more fuel in the 6000-7000rpm area this morning and drove it to work. I don't have my laptop with me so I do some logging tonight after work most likely.

5. the low/mid fuel trims are still dead on.

6. it felt like it got into the power a little later than before, could be the cams or the tune, not sure yet. I literally spent 10 minutes on the tune because I spent most of my time repairing boost leaks last night. DLL confirmed my butt dyno readings.

7. The fact that it went super lean makes me think that once I get the AFR richer and back on target I may be able to add a little more timing and make more power.

8. I ran that one log through DLL and it looked almost exactly the same as the previous DLL I made before the swap was done. 500awhp and 400awtq on 93 octane at 30psi

I think I have 70+ miles on it now and so far I'm very impressed.
