Oh you meant these mods:
Stock intake w/ lid on
Stock filter- about 10k miles on it
Stock intake
750cc RC injectors(left over from sc'er install)
Head- Stage II Laskey head prep w/ 1mm oversized exhaust valves/stock size intake valves
12:1 pistons
Rick's header
T1R testpipe(I believe it is... purchased second-hand)
Invidia exhaust
AEM EMS

VersionJDM has stock head, stock compression, stock displacement, stock header and is only making 14 rwhp less. Now his exhaust probably flows a bit better, but shouldn't you be seeing better numbers?
I understand that you're not too concerned with the dyno numbers, your concerned with the lap times.

If you don't mind me asking, don't the numbers seem a bit low? What AFR were you tuning to?

Safe... yes. Inline knows why and for what I'm using this motor. I'm guessing that they have a vested interest in not having it go ka-pukt, both in terms of immediate replacement cost and negative press. I told them I did not want to have to mess with mixing race gas either. I just needed a low(er) maintenance solution to my sc'er setup.
I haven't uploaded any data from the EMS yet. I'm replacing cv joints, hubs, bearings and installing the BSK this weekend. After the first of the year, perhaps I can forward more exact information.
Clawhammer, peak hp means nothing unless you're into bragging rights. When I was tracking/autox'ing my car AND showing it, that dyno sheet was gold. Now that I'm more interested in real-world performance, I'm looking for more power to help me get out of that corner that I just botched up. My laptimes at Summit in October suggest that the motor was capable- making up for driver error/rust.
Note: Nearly 400hp was real, but only seen at redline. It was still faster than my 2.5L. Boosted will always be faster. That's why I always marvel at those that insist NA is better, 'cause it sure ain't faster!
On a track, smoother is faster. Sometimes the guy with the most power isn't always the fastest. I'm hoping to become a better driver; one that is no longer dependent on power to be fast.

stock compression ratio? If so then with an ems tuned you'll be at 240whp. I believe there was a member that made 240whp with the inlinepro 2.5l and ems. then he made 250ish with an exhaust added to it. Torque is going to be nice!
Man I hope you got higher compression. maybe soething like 12.1, I think this is a great streetable ratio for pump gas.

And I'll probably just be doing my tuning with an VAFC II, at least to start. I'd like to remain on the stock ECU as long as possible.

too bad you just sold of your EMS didnt you?
The theory behind using 550cc injectors with the 2.5L and the stock ECU is that it is it's own compensation. The amount of fuel the 550's add is comparable in ratio to the added air being taken in from the 2.5L, as far as daily driving is concerned. And of course, the AFC will be there to tune for WOT.

Right now I have an 11.5:1 compression motor on order. I'm probably going to stay at or around there since I will be running this on a stock ECU, but perhaps I can go to 11.7 or 11.8.
And I'll probably just be doing my tuning with an VAFC II, at least to start. I'd like to remain on the stock ECU as long as possible.

well stated.
