This setup sounds awesome. By the way, what does the Fuel Pressure Regulator do? I mean, it sounds self-explanatory, but Im curious why some setups use them and some dont.

I'm raising the fuel pressure in the fuel rails which will allow more fuel out of the injectors.. Since the power output is greater with the race gas file, we need more fuel.. Racing or track applications require the extra safety margin.

OK Jon, It has been more than a year now... how is the car working?

I am planning on doing the Stage 2 from Kevin and need feedback from folks that have done it and are still with it (since I know a few have moved on to the other stages... power freaks!! ).

Anyone with a year or two on their Stage 2 setup?

Words of wisdom?

Kevin: On your basic tune...what duty cycle to the injectors run at when at WOT?

Kevin

Chuck it will vary between tunes and locations (fuel octane).

Give me a ring tomorrow..

Been on some version of this stage for 3 years....love it. Instant power, very quick....no blown MAFs. I am at the limit of fuel however and would need injectors to go any father....also at over 5300 feet elevation.

Cool! How many miles on that tune? Did you go with the clutch package as well (LWF, etc.) ?? Thank you

Yes the GT3RS clutch package w/LWFW...look at the link in my sig. Probably about 7000 on the tune.
