i guess paired with this upcoming flash and injen intake should have some great numbers. BTW did you have an aftermarket intake while on dyno?

I hear the injen actually doesn't as well because it still sucks in a lot of hot air since its not enclosed. |

Oh wow. Congrats on that. What did they do to gain that? Made it run richer? Any change to the Valvetronic? I'm so curious, haha.

I'll ask Tony, all I really know is they are basically messing with the air/fuel ratios and a few other tricks. I'll let him post some kind of an explanation up when he feels ready to.

Yeah its a pretty nice setup if you are running an intake/exhaust combo. You might even see a tiny bit more gains than from mine cuz I only have the intake.

Haha. Alright. Sounds good to me. I just always thought that messing with the valvetronic could really help produce gains.

the way the valvetronic works is very complicated, so I doubt they are messing with it just yet. those numbers are better indicators of fuel and timing changes. Once you start getting into valve lift, you can see bigger gains, but because the valvetronic continuously alters lift depending on speed, load, throttle position, etc., it will be much harder to tune.
Maybe they can figure out a way to patch-in the higher lift valvetronic programming from a 330, and then tune the fuel and timing to match the 328's engine and intake. |

Yeah I'd bet the vavletronic is left alone at this point.

Haha well Tony kept them and I'm not going to "publish" anything until they tell me its the best tune they have for the car. I'll be trying to get back in there sometime in the next week or two for them to finish up. After that, I'll make sure I post up my dynos and all that... though since LETMotorsports isn't a vendor I don't know what the can offically say/publish on these forums w/o getting in trouble.
