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

The fuel pump re-wire and a wideband to show you how pig rich the car is already running.

I had a rewired FD fuel pump.

Upgraded stock turbo (.46 clip, etc)

Yeah with that setup I wouldnt really worry. If you are still concerned however get a nice set of gauges and a wideband to calm your nerves.

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.

I never said it would be cheap I said if you are still concerned ;)
