Need Help With Base Tune

Okay so I've been tunning my car for the past week and it feels like I haven't made any advances. I have the speedcorps mani, 16g turbo with ported 10.5 hs, ported stock o2 housing, 3" dp, 3" hfc, 3" catback, 440cc injectors, 12:1 fmu, walbro 255, bored fuel rail, stock evo intake, intercooler and piping.

This is the tune I currently have and leans out under boost.

Here is the most current log.

Any help for a good map to start me off with will be greatly appreciated. I can adjust the timing and such, I just need help with injector latencies and octane fuel maps.

Thanks

This is the tune I currently have and doesn't feel right at all.
MAP

Here are some logs that I recorded with different tunes.
10/06/09
10/05/09

Any help for a good map to start me off with will be greatly appreciated. I can adjust the timing and such, I just need help with injector latencies and octane fuel maps.

Thanks

i say first off lets smooth out both of your maps a little more. after taking a look they kinda loo all over the place in the higher load and rpm values. whats the car acting like?

Were you WOT in either of those logs? The highest TPS% I'm seeing is around 45% or so. I'm not sure if there's no knock because you're not WOT or because the tune is very conservative.

No I haven't done any WOT pulls because it ends up spiking to 15 psi. I'm just waiting for my wastegate spring to come in.

Updated first post.

I edited my fuel maps and smoothed them out a bit. But now I'm running lean under boost.
Some help please.

Let me know what happens on your end. My problem is pretty similar: 9psi, running lean under boost, fuel tables are maxed out. Currently using walbro 255, wrx 440cc injectors and stock fpr.

Are you using the stock MAF?

This thread will help (last couple pages) https://www.evolutionm.net/forums/la...der-boost.html
You need adjust your MAF scaling.
