I have the ebay kit with a garrett gt70. I have a comp xer 230/230 .591/.591 and ss4000. Plan on running between 7-10psi

Heads: Are my 241 heads going to hinder the 10psi?

Fueling: will my 60lb injectors and walbro 340 suffice?

Tuning: should I run the 2 bar setup or is it possible to get a nice tune from maf oem map sensor?

You should go 2 bar and the 60lbers and 340 pump will be fine.

Anyone else? What about the heads and 10psi?

Heads are fine at 10psi but will keep the compression a little high for my liking @ 10psi, but others run it perfectly fine!

I have a set of 317's that I may throw on later. I really don't feel like taking it all apart now. I'll probably get the 317's ported and throw in some bigger valves.

Stock heads will be fine but I would suggest putting some springs/retainers in there...we have seen valve float at 8-9psi on stock springs.

MAF will work, but 2 bar is MUCH better. Go with that and keep your 60lb injectors and walbro. Should be a ton of fun to drive.

maf should be fine with 10psi, or under 600rwhp, but 2 bar might work better.

i like the maf for that hp level

I have prc dual springs and titanium retainers on there already. I'm hoping to see around 550rwhp with 10psi, do you think its realistic? I'm just not understanding how a stock map sensor will work since it doesn't account for any pressure 0psi and the boost with make it above the 0psi

Thanks for the input guys.

Because for WOT fueling on a stock setup, the MAF does the calculations, not the MAP.

The MAF tune will be alright, but you'll still need a 2 bar MAP sensor installed on the intake. If you keep the stock MAP sensor installed, the computer will not be aware of the additional manifold pressure above atmospheric (any boost at all) due to the stock MAP sensor being unable to detect it.
I think you will make more power at the same boost level, and definitely hit your 550rwhp goal with the 2 bar SD tune. BUT, this may require more than 91 octane with stock compression, or less than 10psi of boost.
