Datamaster run and fuel injector advice

Well, I finally got around to doing some logged runs on the car last night with Datamaster. The car is a stock 97 LT4 Firehawk with a tune from Madwolf. For those unfamiliar with them, the LT4 Firehawks got a balanced and blueprint factory LT4 (no hotcam, just standard LT4 cam), but used the stock LT1 ECM and fuel injectors.

Here's the run in a csv file:

From the Injetor duty cycle numbers, it looks like I'm pretty much pushing the limit of the current injectors (peaking around 97% at 6000rpm). Granted, I'm running past where a stock LT1 would, but is this normal for this power level? Which injectors should I step up to?

Any other suggestions?

Oh yeah, guess I should post my last dyno with A/F too:

I haven't had it to the dyno and logged it with Datamaster at the same time yet, so I'm not sure how the O2s relate from a highway to dyno run.
