Neither Kits include fuel system upgrades. I am pretty sure the APS does come with the cheasy bosch plastic bypass valves. Maybe the line item is for an upgrade?

I have great replacement DV's for the Bosch's by way of Hyperboost HX Stealth. They react much faster and have no rubber parts to fail unlike the Bosch series. HX Valves will handle more boost than you could throw at it for the C5/6's etc... Usually they are 169 each but since pairs are needed I will do them for 300 shipped for CF Members. Plenty in stock ready to go.
Here is some more info, the latest valve now looks exactly like the Bosch and is so close it fools Audi/VW dealer techs all the time. I would have to say I sell about 15 of these a week +/- of course.
The TTi Stage X kits come with a TiAL 50mm by pass valve w/aluminum CNC mounting flange pre-welded on the intercooler for installation ease, designed so compressor surge is never an issue.
Neither kit comes with injectors or other fuel system upgrades as they can't possibly have one fuel system for every car and every power level goal.
Thats probably why the TTIX is a better kit.....No kit will include injectors or Fuel System........Injectors around 300.00 - 400.00 and fuel system ECS 1800.00 so you are probably a little short to put the kit together. When I purchased my D1SC from Andy, I was half way there to complete the install....and Im not including the forged block and internals. I think it was close to 20,000.00 by the time I had the Engine and Pwertrain done.
What does transmission type have to do with a BOV?
TiAL Blow-off Valve
9 psi or 11 psi TiAL Blow-off Valve
Recommended for manual transmissions to maintain boost during shifts
I agree it helps reduce surges too on the thrust bearing but on a rear mount turbo in my case how much do you really get...Its like dual wastegates..if you dont have any boost creep is it worth it? I dont have any so im keeping one wastegate. I think a BOV is for serious hp.
Don't get me wrong ... I mostly like what I see about APS. Just hopeing that the 'batteries would be included'.
You just need to add the fuel system of your choice..............other than that the APS is the most complete C5 twin turbo package available.................even includes a twin three inch 304 stainless steel exhaust system right through to the rear muffler assembly.
