OEM systems/tune compensates for bolt-ons?
I've heard differing stories on this. Never worked with newer GM motors with computers.
Can these newer GM computer systems adjust A/F for CAI and exhaust bolt-ons so they don't run too lean? Is there a general rule limit to A/F tolerance adjustments? (I understand a tune can address more elaborate mods)
Looking at CAI, Shorty's and CAT-back so I can keep the stock dual CATs and sensor locations, hopefully without throwing a check engine warning or running to lean.
I don't want to void engine/powertrain warranty just just yet. My dealer stopped doing FI installs due to warranty issues with owners. I asked about drop-shipping to tuner(ex. Hennesey), but since Hawaii has geographic limitations, my local dealer warranty coverage is conservative for obvious reasons.
Unlike Ford, a friends Shelby got the full FI, suspension, and tune, with a Ford limited warranty from a local dealer. Too bad the new GM doesn't offer that type of service.
