I'm going to be campaigning a 2.0 turbo Genesis Coupe 5 speed. Not the 274 hp direct injection version, the earlier one. The people preparing the car have demonstrated a very foolish propensity for listening to my advice regarding upgrades and setup.
Anything I should know? I'm very new to this platform.
You are the semi-professional racecar driver and amateur tattoo artist.
How about this. On oval tracks don't take too many rights. You can actually use that for any car so that's a bonus! 
I'm the hopefully gonna race on somebody else's dime next year guy. 
And even if it falls through, they've let me in on a lot of the engineering stuff. Part of the aero package on this thing was my design.
I think the one I drove had the newer engine, but this may be an issue with the earlier ones as well- it took FOREVER to get boost back in between shifts. Worse than your average turbo car by far. Finding a way around that would probably be hugely beneficial on a race track.
Cool. That's actually a problem I'm already trying to solve (in a completely different project) with regenerative braking and compressed air.
What rules are we playing by? I agree with the insanely bad turbo lag comment. I don't know if it's just oversized (which seems weird since it's only got 210 hp I think). Or what but that would be my first thing to tackle
lol that car is unrecognizable as a genesis to me. The headlights throw me off.

It's a Tuscani (2g Tiburon). Last year's car. I actually wish I could use it next year, too, but sponsors evidently said no to using an older chassis.
Lighter and more powerful are less important than shiny and currently in production to the people writing the checks.
I've only got a couple of autocross runs in 2 Genesis coupes, and all I remember is massive understeer.
I used to have a manual trans forte koup and the (drive by wire) throttle response was rather wonky. sometimes great, others horrible. any chance that might be part of the lag problem, poor DBW programming?
In reply to bluej:
That's what it felt like to me- I think it even closed the throttle when I tried flat shifting it!
arent the manual transmissions in them fairly sucky to use?
Which part of the aero did you do? (please say the stickers....)
Calling Rhys Millen...

I would think that adding a blow-off valve would cure that issue.
Didn't RMR offer suspension stuff for them?
When I drove them the manual was bad bad bad. Vague and sloppy. The 8 speed auto was much better at keeping it in boost and more fun to drive.
I will probably be banned for saying such blasphemy.

Not sure on RMR, but I know Feals does. They sponsor Aurimas Bakchis' Genesis drift car. In pro drifting, the Genesis has a bit of a reputation as a career killer

???
How would venting boost spikes to atmosphere make boost come back quicker after shifts? 99% sure the Genesis has a stock bypass valve that just recirculates that air, which is more beneficial than venting it externally...
Wait if the car is drive by wire why not do what Porsche does?
Put in a pause statement on the throttle body and cut fuel to the cylinders when you lift off. You will have to figure out the timing (probably around a second depending on the response time) but that way the Turbo doesn't get the back pressure hit from the throttle body closing causing it to lose boost but you get the momentary drop in power by having no fuel.
Just a thought.
In reply to Flight Service:
Why fuel, and why throttle? I say cut ignition, and only do it when the clutch is in. Keep the throttle open while shifting, and dump some fuel into that turbine to keep it spinning!

Spark cut would work, but it's harder on the turbo and only an option if the thing is catless.

Old mis-fire technique used in Group B. You don't lose boost for a longer amount of time, one issue, get it wrong you eat a turbo immediately, get it right and you replace it after each race. Turbos like hot gas not exploding fuel.
Porsche is using the fuel cut out on production cars now. Cleaner, no damage to stuff and the car gets to keep boost a little while longer, even if it isn't as long as the mis-fire method.

Was it grinding, quivering understeer or was it just conservative tuning, do you think?

Why not compressed air?
