Ohlins are on! Don't mind my hideous calipers left over from the previous owner, I just picked up supplies to refinish them. I also just ordered stainless lines and some Motul fluid and am planning on bleeding out ALL of the gross fluid that's left in there. I also spent some serious time and sealed my system all up, and for once in my life I have 0 boost leaks whatsoever. Car feels great and I think it's officially ready for the tune tomorrow! VD numbers coming tomorrow night. 

Monster truck status! Getting a good alignment with corner balancing and stuffs soon.

She's finally tuned....well......almost. 

(Story time)

Ever since I finished the build and had a base tune on the car, it would always go ridiculously lean whenever I would mash the gas, but not in a "my car isn't tuned way". So, last night, I got the car ready and went over everything. After I fixed all of my boost leaks (some were huge), the car wouldn't idle worth a damn. 

When I got there for some t00nage tonight, Mr. Karl saw that my front 02 wasn't working. He had an extra one, so he grabbed it, threw it on, and still no luck. We came to the conclusion that something was probably muffed up when the car was running on AEM. We (he) decided that running it in open loop would work out, and it did. So, we started getting into making some boost and noticed that any time I hit the gas quickly the car would go ridiculously lean, despite what the map called for. We swapped out injectors for stock with no luck. We then tested my Fuel Lab AFPR (shooting some compressed air in the line to check for response), as that was one of our last guesses as to why it would go lean despite how much fuel he was throwing into the map. While it worked, a few times it would randomly not respond. So, after being almost stumped and ready to call it quits, he had an extra stock FPR (keep in mind I'm running a rewired 400), so we threw it on just for kicks.

Boom, problem solved. The most expensive piece of my fuel system (sadly) is inconsistently not building pressure when it should be. So, he did what he could before we had to part ways, but we ended up with somewhere around 400/400 (VD) on 93 octane, with a bunch of fine tuning to go, which was my main goal. So far, the car feels freaking great, and the torque hit is ridiculous. 

I can't thank Karl (KP Tuning, mxguy186) enough for lending his time and expertise far past what the tune called for without blinking an eye.

Feels so good to have this thing back in action. Oh, and the Ohlins are the best thing that have ever happened to my car.
