Hi All,

I bought an ITS '87 RX-7 last month, I still have not even seen it yet. I've been reading as much as I can find. I'm looking at what some others have done, and the chip modification has me wondering. I have a BMW, and the chip upgrade to the S-52 engine was affordable and a 10 minute DIY project.

After reading the post regarding "2nd Gen ECU Mod", I'm thinking the Mazda engine is not so easy. What options are there, and what gains can you expect? I assume they are legal, even though some wish they were not.

The car is at the shop that built it, and will cost alot to take it back, so I'd like to evaluate it having it done before I bring it home.

Thanks

Steve
