I have a 99 civic ex with a 99 integra gsr swap in it and im currently running a si ecu (p2t)..would it make a difference in power if i got the gsr ecu (p72), considering thats its dual stage vtec?? i need feedback on this little problem i have..It just seems like its not making the power that its suppost to read or i dont know..what would it do if i ran an si ecu with a gsr swap??
