Hypertech or Osiris(UpRev)?
The 0-60 throttle restriction removal does work. I currently have that installed and it removes basically all the lag. As far as a/f ratio, I doubt it would fix your leaned out issue.
kinda of a waste if you were told it isent going to get your A/F back where it needs to be.. i would be uprev..of your getting headers catback and have the stillen your going to be lean
Just talked to Hypertech's tech support, and it seems like the device doesn't correct any A/F ratios (if anything, he said it might lean things out a bit!)..
But since I found a sweet deal for it online, I guess I'm going to dyno my car with the new mods first, then again with hypertech programming and see how the A/F's look like.. If things are too lean for my taste, expect to see a Hypertech for sale around here pretty soon!
