There are no aftermarket chips that will make any difference on stock olds 307 and a chevy 305. Those chips just add a little bit more timing thats it dont waste your money.
Know if you can find a Crane EPS System it will wake up a stock 307 it wont give you an extra 100 hp but you will notice a huge difference over a stock ECM, I have one in my Hurst in its original design. Problem with the Crane System is they made less than hundred of them.

For a Chevy 305, the GM ZZ4 chip is a nice bump up. But GM never bothered with Olds 307s.

That is cool as hell, I considered the open tunable TBI ECM's, same idea.

Don't forget about the aftermarket. Edelbrock did the smog legal headers and Y pipe for 305's. Too bad Edelbrock didn't copy the FE3X shorty headers and Y pipe for the Hurst/Olds and 442. Olds claimed 30 hp with ram air. Of course Ford had the brain's to put on actual duals and headers from the factory along with much less weight. No wonder the Ford 5L HO was the king of the streets. The GN was rare enough that it barely counted in our area.

To use a ZZ4 chip you need a 87-88 mcss ECM. ZZ4 has a better advance curve and a EGR delete plus a better TCC that's it. The beauty of Crane System is you can make all kinds of adjustments at any time on a stock engine or mild to wild engine. With an aftermarket chip or ZZ4 chip you cant make adjustment. Clone Tie Pilot, dont you have this system?

Yep, but have not had time to play with it yet. The chip I have is one of Bitflipper's, which has enabled EGR, Baro sensor, and disabled automatic timing advance when a scanner is plugged in.
