is there a way to adjust the throttle cable? yes, i've done a TBA.
so I went and beat on my car a bit today... I left my house thinking I'd just take it around the block to see if i could reproduce the lack of boost I was seeing last night, and I ended up going for a 1.5 hr drive!
here's my discovery: if i push down hard on the gas pedal -- almost PAST WOT, so much that the pedal digs into the floor and hurts my foot -- i can get a couple extra pounds of boost, and the car is noticably quicker.
I did a TBA recently -- within the last couple hundred miles -- so I'm pretty sure that's not the problem.
Could it be the throttle cable itself? Should I just clean my throttle body?
IIRC, the last set of logs that measured throttle angle were in the low 70s (73) when I thought I was WOT... and if i pushed harder it went to 78... what is true WOT throttle angle on nDBW?
also, if my car was not really WOT on the dyno, then it was using the fuel trims, which had not yet updated adjusted for the new programming/injectors/fuel pressure. Dammit!

TJ: So...now that you have had the evolution racewerks FMIC for a few weeks now...
what is your opinion on it? What performance gains did you see/feel? How much was the pressure drop? IIRC, the install was fairly easy and not too big of fitment issues correct? Just looking whether i should look into this fmic..racetech/spp..evoms..or osmething else when it comes summer time.
Also..if you dont mind, what was the cost of it??

Well.... Difficult to really answer...
The problem is that I was without the car for 4 weeks while it was getting installed, so a before & after is a little hard to come by.
The logs show a most certain drop in IATs, and definitely keep it cool enough for the PC-16. Since my MAF was already maxed out at 187g/s, it's hard to say how much was gained.
The fitment did require a good amount of trimming, though, I was told.
It should be known that I was the first B5 A4 that this thing went into; it had been dropped into a Passat (incidently, the one that was also the test vehicle for the new FXK04 GIAC program) and apparently that bumper was much easier to work with. The 3" Garrett Core is just really thick!
If anything there was maybe 1 PSI drop? I was thinking there was possibly more, but now with this whole throttle cable thing... who knows.
I can't say how much I paid for it (I'm under a NDA for that), but I believe retail will be around $1100 for the whole kit.
There's a bunch more info on it on AZ; look for "Bitterchild"--- all the threads about it are linked in his sig.
