Can I drive to Dyno tune with 42lb's?

I have installed a Vortec supercharger and I am looking at getting it dyno tuned. I am going to go with 42lb injectors along with the corresponding mass air meter.

If I stay out of boost, will I be able to drive this to the dyno safely? It is about 60 miles.

Thanks
 
When I had my charger, I did the same thing. I turned my FP down to like 30 psi because of the 42's, and tried to keep the RPMs below 2500. It didnt idle very well, but drove fine. I had to drive about 50 miles. Good luck
 
I talked with Dan and I am going to get my tune done at Pro-Dyno.

I am not sure what way to go with the 42lb injectors. I have to drive about 100 miles the morning of the tune. Dan said that the car might run okay or might not with the 42's and no tune.

Would I be better off to just bring them with me and have him install them along with the meter? I was looking at putting them in this weekend.

I guess my main concern is being able to drive the 100 miles with no issues, and not hurt the car. Would the plugs need changed after driving it like that? Would it be too rich?
 
There's really no way to say for certain. If you swap in 42's with a matching MAF meter the car will probably run. It may run rich and it may run lean. The safe side would be rich, but you're not going to hurt anything if it's lean if you drive like grandma. You'll want to bring good used plugs with you because you may (read probably) foul them. No point doing a tune on some iffy spark plugs.

You don't want fresh plugs because they run differently for the first couple hundred miles, why tune with fresh plugs when you're almost never going to be using fresh plugs?

You do run the chance however that it will not run without the tune, if so you're going to end up doing the job 3 times over to go to 42's, back to stock, back to 42's once you're there.
 
I see what your saying....

I think might just bring them with me and pay an hour labor and have them install them. (or I could get there early and do it in the parking lot....:)

I am thinking bringing them would be the safest bet because I don't want to have to put back in the 19's and change the mass air meter too. (it is on the end of an anderson power pipe, so it isn't the easist to get to.)

Then my plugs will be good because they will have about 300 miles on them once I get to the dyno.

Thanks for the input...:nice:

Now that sounds like a plan. :nice:
