Anyone out there with 04 RS had custom flash like me?

Wondering if 04RS ECU is same as other 04 ECU from GSR.

After 272 cams and flash w/ supporting modds (intake, tbe, bov...) got about 300 whp on dynojet. Also, I do use hiflow cat instead of testpipe.

I am not sure if this output should be specific to 04 RS. I saw a 03 GSR with similar setup netting 325whp. he too had hiflow cat.

only difference was mine is magnaflow vs his catco cat...

anyone w/ insight to this???

 

Who flashed your car? That is weak. You should have another 30 HP easily on a Dynojet.

 

There's no differentiation between 04 RS and any other 04 ECU when looking up part numbers.

 

I'm almost possitive the ECU's are the exact same. Sucks your numbers are so low. My 04 RS numbers are in my sig with the mods listed.

 

dude,

we both have similar setup, you probably are running catless though.

But still 340+ on Mustand dyno??? are you sure its not dynojet?

 

Nope we all dyno on Mustang's here. I put down 352 on it. It's the GSC cams tke 413 and I run. They are very good!
