305 to 350 swap

I am planning on swapping out the stock tbi 305 for a mildly built 350 block i have i the garage. it is out of a 1969 chevelle and i am planning on keeping all of the emissions and fuel injection equipment from the stock 305 motor. The 350 motor has 202 double hump heads so instead of drilling out the tbi manifold, i will be installing a tbi adapter plate for the 4bbl. carb. manifold currently on it. this is my first obd car motor swap so i was wondering what the cheapest and most effective way is to upgrade the chip in the car. Any suggestions???

Well it's a lot more "dummy proof" than the "burn your own" chip setups available.

The code & interface are just as usable and effective as some very high dollar tuning equipment.

You don't have to take my word for it,..just ask anyone who uses RBob's stuff.

For the tbi, I'm assuming I will need bigger injectors and need to regulate the flow for more psi. How do I regulate the flow and where could I find injectors for this swap? Everything I've found online have been stock replacement.
