like did he NEED it cause his AFR was unsafe or did he get it to squeeze out all the HP possible?my friend needed a tune after BBK LT and o/r x
okie doke. that's exactly what i was wanting to know. i'm thinkin i should just get a mail order tune since i won't be going home until the 3rd. how's vmp? what's their turn around time like?The A/F is going to change but it's only going to be a few tenths of a point. So, yes you'll be fine to drive it for a little bit until you get a tune. It's going to throw a CEL, probably. So order a tune for them and you can drive it until you get it. Unless you've got a tune that's already on the ragged edge you'll be fine.
