Do I need more fuel mods?
I'm almost done breaking in my engine, finally, 200 or so miles left and this thing will be ready to go full boost.
I want to turn it up to around 10-11psi, but I'm only running 550's all the way around. The problem is I'm scared the car will run to lean on top because I pretty much only have a FD fuel pump as a fuel mod. It's not the 10psi that bothers me, its the boost spikes.
What do you guys think? Should I add another fuel mod?

If youre worried about fuel do a search for fuel pump rewiring and rewire your fuel pump to keep the voltage up. As for the boost issue what kind of a setup are you running? Stock turbo and stock wg? If so do a search on wastegate porting or check out www.fc3spro.com
Um wide band == Money.
For like $50 usually you can stop by a Dyno place run it and get an AFR sheet. That way you don't have to buy something you'll only really use if your a tuning freak or have a monster engine.
