Fast 102 untuned Can I run the fast 102/102 combo safely (~ 1000 miles) until I get a re-tune? The mileage is cause I my MWC 9" comes in next week so I would prefer to break it in and tuner is couple of hours away.
Car is H/C tuned with stock 28.8 lb injectors. I am about to do the ls6 valley cover mod and was just going to put the ls6 intake back on and have tuner install the FAST w/42lb injectors. Makes better since to install the FAST w/stock injectors and just swap out to the 42 for the re-tune.
Thx!

I think you can.
I moved from a 78mm throttle body to a 90mm throttle body on my LS6. My out of town tuner told me it would be no problem and it was not. The driveabilty was essentially unaffected and a check of the full throttle air-to-fuel checked okay at a local dyno facility.
Later, also between tunes, I upgraded to a FAST 102 intake albeit with the same 90mm throttle body and the car was still pretty well behaved until I finally got to my tuner for a retune.
And, as you said, do not install differenti injectors until your tuner is present.

You could probably do it but the car will probably drive terrible untuned. That's a lot more air coming in than a LS1/6 intake assuming that is what is on the car. It will probably have a pretty high idle. Each one is a little different but I don't think it will be happy!
