How to control tpi/stealthram system
so, I'm in Virginia and if anyone's ever been here before you know you can easily experience 3 seasons in 1 day. I really want to build an extreme 350 or 383, and I want it to run smooth for having a LARGE cam in it. If I stick with the 350 I wanna go with an LT4 hotcam, if I go with the 383 and a nice set of heads I wanna go with a .574/.580 and 274/280 duration comp cams setup with 2.08 intake valves and 210 AFR heads.
so I really need some fuel injection to make this car fun and comfortable to drive and reliable. Im SICK of my carbs. So what I'd like to do is buy a TPI setup, sell the intake with runners and then use some of that money to buy a used stealthram intake and fuel rail. My question is, how will I use the TPI computer to control such a system? or would I need to replace the ECU with an aftermarket one?? what's the cheapest and most reasonable way to get this done?
I really dont know much about computer control on high modded engines. any help would be appreciated

Re: How to control tpi/stealthram system
Basically, you're just looking to do an intake swap. The factory ECM will run the new engine with some time spent tuning.
