1995 mustang gt ECU question

[1990Chevy350]

im trying to see what ecu goes in my 95 gt.. i believe its the TM40 ECU im not sure though but my question is does anybody know if i put a diff ecu like out of a cobra r or something more upgraded how much of a horsepower gain should i get? and does anyone know what ecu to upgrade to?

You need a stock 95 cougar,mustang v8,ecu... if you get a cobra 95 ecu it will hurt your hp due to the timing,and intake,injectors are stock gt ones... and the price is hella more.

ok because the one i have is the oem ecu and its chipped.. so i guess i should just stick to that one..
