Default Installing larger injectors, need a base tune?

So, after reading, it looks like everyone agrees that before you start your car with bigger injectors, you need to have a base tune put in for those injectors.

I will be putting in 42# injectors on my H/C/I LS1 build, but I have to drive 120miles to my tuner. I guess I should keep the stockers in, make the trip, then swap out the injectors once I get there. Is this the way everyone else that has to travel to your tuner does it?

Thanks, James.

Do not even try to drive with a 42lb swap without changing the IFR table to relect the new injectors. It will dump tons of fuel in and will foul plugs in a matter on a minute or two. Swap them when you get to your tuner.

As already stated, swap them after you get to your tuner. That's too far to drive on an incorrect tune.

I thought about runing it with the stockers to make sure everything was good, then swap out to the bigger injectors and trailor it down there. I've got a truck to pull it but no trailor....I might could find a person to loan me one though

Just drive it with the stock injectors down there, they wont max out as long as you dont go WOT.

I was just thinking it would be easier to change them in my garage instead of outside, but I'm probably making this out to be harder than it actually is...which I do alot

If you change them in the garage you will have to tune the IFR table before you start the car or else is will cause major flooding of the engine and will foul the plugs. The injector swap and tune must be done together.

BTW an injector swap takes about 30 minutes to do and is very easy.
