I'm puttin the LTs and prochamber in tomorrow and was wondering what your guys' AF ratio was before tuning. That is all, lol.

no, i mean like how much did the LTs throw off the AFR before you tuned for the LTs? was it less than a point of difference? i know a tune is not needed for the LTs in most cases, but i was just wonderin about how much change in AFR i'd be looking at in the most ideal scenario

my friend needed a tune after BBK LT and o/r x

like did he NEED it cause his AFR was unsafe or did he get it to squeeze out all the HP possible?

what i'm asking is will my AFR be unsafe to the point that i can't drive it until i get it tuned? i've got no problem driving it liberally for a couple days, i just want to be able to get to my tuner without putting the car on a trailor

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.

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?
