I am new to TPI Systems. I want to remove the 305 TPI and install a 350 CI. Will the TPI from the 305 work? If so what do I need to do other than injectors? Please help if you can. Thanks.

You'll need to change the PROM to a 350 one.
Also the 350 you use will have to have 87and up style heads if your car is an 89. You'll also need a knock sensor for a 350.

You'll need the following:

the 350
350 knock sensor
350 memcal
22 lb injectors


All your other TPI parts will work fine.
