Hi, Guest
It IS a cool mod, but really in my mind you'd have to be turbo'ed or massively N/A modded to make use of it. I felt an immediate difference driving it with the mod done, but not in the terms of big numbers at the wheels or anything.
With that said, I'm happy to put the SPI back the way it was (at least in that context) because it really does sap the fuel economy. Had I tuned it with an X-Cal or something, it might have been manageable. Same for having the 50% UDP I want installed. Neither of those things were at hand, so I have to revert it for now.
EDIT - well, my impressions after driving the SPI for about 2 weeks with the IMRC mod. I need a HECK of a lot more mods or a really good clean-up tune to make that worthwhile.
They make mention of the fact you lose some bottom end when you do the mod... make that you lose a LOT of bottom end. I was driving just to the mall last night with Sara, and DAMN. I can actually move off the line and not have to wait for 3000+ RPMs for acceleration.
What's more, in retrospect, I don't really notice the IMRC.
