Currently my car just has the Fabspeed exhaust in my sig. However, sitting in my garage as we speak are a set of headers, a Cobb V3 and a new 3" cat less exhaust.
Do I need to worry about fueling at this point of the game and if so what should i do?

Thanks,
Rich

 

You should be fine until you add new turbos. Generally on regular fuel you can go with larger injectors and get up to 700 crank. Then add pumps/lines for more. But then if you are looking at running E85 then you will need more fueling regardless.

Let me know if I can help with any of it and tuning. The Cobb 1000's are awesome.

 

The tune will most likely compensate for the additional fueling that's required. But from your mod list I don't think you'll need to worry about any fuel upgrades (injectors, FPs, etc.)

 

With just a tune and exhaust my IDC % was over 100

Log it with the injection times and calculate your own IDC% and see if the current set up is sufficient

 

On an S or X50 that can happen. But the 16's won't need that much fuel.

 

Should I look into a 5bar fpr just to be safe?

 

WOW. Wouldn't have thought there would be more turbo than injector (550CC) even on the X50. Good to know though!

 

What wolfedge failed to mention was he is on e85.huge difference in fueling needs

 

No at that time I was on an old GIAC tune, AWE exhaust and 93 octane IDC% was near 130 at times as tune was very rich

here is a log
