APS ST - The goods
We got the car on the road last night after what turned out to be lengthy guage install.
I talked to GRD about the amount of preload to run, and got that all set to go. We got things buttoned up and put the shield on under the turbo, and headed out for a test drive. HOLY ****, the car felt awesome. Decently comparable to the twins out of box. A bit more turbo lag, but saying that is being picky.
With the weather being cold (actually relatively warm for us now) and the road conditions, we only ran it up to about 6 grand or so. The car held at just below 10 psi the ENTIRE time. We could not see any boost tapering at all.
At this point, it doesn't seem to be afflicted by the check valve issue, though we really didn't let it sit since the test drive. Still I am feeling confident that it won't.
The only 'bad' we had is that occasionally, we are getting a bit of rattle from the heat shield near the turbo. with clearances so tight I expected a rattle or two. We will get the car up on the hoist and see if we can bend the shields a little bit more to rememdy/prevent this.
I had read about numerous issues with this kit, the most concerning to me were the check valve and boost tapering, both of which, we had no trouble with at this point.
All in all, the install took a little longer than I expected, but was worth it in the end.
FYI:
>2004 touring 6spd - with 22K on the odometer
>only other engine mod was a UR crank pulley
>Car is fitted with APS ST exhaust
>Preload on the actuator was set to just about 1.5 holes. About 2 turns more on the rod than the APS video demonstrates
> AFR held at 11.2-11.4 untill about 4600 where it dropped below 11 (AEM wideband doesn't read below 11)
>With the addition of the new clutch line in the kit, we noticed a bit stiffer clutch pedal
>Clutch won't last

Before someone else asks:
can't, the only one around me blew up - I am 100% serious
And everyone else around me that wants FI is smart enough to choose APS
Blake (the owner of the APS ST Z) drove in the TN car before it popped - he can let you know how the APS ST compares

Zivman - I dont think you'll have any issues with the checkvalve. APS found that there were 20 or so defective valves and the situation should be rectified by now....
Just to be on the safe side I'd go ahead and get the revised electronic solenoid from GRD so you don't have any bigger issues later on like my expensive MAF sensor being replaced.

The kit was one that was purchased during the original group buy. The car was driven until today and is now put away till march. At that time, the car will be going to GRD for a tune. I think the best course of action is to have GRD replace it when it goes down for the tune.
