Superstock map running SUPER LEAN

[mxjosh82]

Hey guys, I have a MSP with hard piping, front mount, 3" j-pipe back catless exhaust, and boost controller peaking at 9psi holding at 7-8psi right now and the superstock map is making my car run insanely lean under like 4500 rpm (12-high 13 AFR) at any boost pressure. I know everyone uses this to start tuning, but this is too dangerous for me! Please Help!

Sounds like a lack of fuel to me alot of upgrades but no fuel support

Or a vacuum leak

What? What "fuel support" are you suggesting other than a simple retune of the SSAFC? I've got a tubular manifold, Pope 3" downpipe, 3" catless exhaust, 2.5" hard pipes, FMIC and I'm running 11.8-12.2 AFRs under WOT on 10psi. I can change that as I like... You know how? The Split Second Air Fuel Controller...

My thoughts exactly. I have seen multiple people like you running way more bolt ons than me with only a SSAFC no problem. I am just wondering why my supermap is running so lean when everyone else is saying it is a great starting point. It is getting pretty cool by me ( I live in Ohio), but I thought colder, more dense air made the car run richer. Correct me if I am wrong. I had to add a bunch of fuel last night just to make it safe to drive and get into low boost while accelerating.

No, it'll lean it out. I'd reload the superstock MAP.

Maybe it was just how cold it was last night when I did a couple logs (it was in the 40's)? But I'll try to reload it. I am gong to throw the Winter FMIC map on for the hell of it too, to get some readings and see whats up.
