HTH with a perforated waste gate hose on the 10v

Was faster than the wife's 964 though. Until the ignition cut at overboost
;-)

I assume the wastegate diaphragm is good.   The bad diaphragm causes a surge
of power, more so than normal, followed by a sudden cut-off of power
(ignition cut-ff).   You're not having that problem, are you?    Shin

Hello-

After six years of nuturing my AVANT with the goal of chipping it when 'all
was ready' including a good price on a used set, did so about 3 months ago.
Boost was as good as 1.8 once or twice before the mod on cool mornings ( as
cool as it gets in San Diego), sampco hoses, fresh most everything. At 196k
attaining 1.5 -1.6 has been a pretty good sign that it was ready for the
added stress of chipping, right?
Now difficult to achieve 1.4, and gobbling gas. Biggest symtom was teh sharp
burp or cut-out while reving- up under load.  Archives lead to  Wastegate
Spring. Trying to determine which to go to (or whatever) I have had a bit of
back in forth e-mails with Intended Acceleration, and I guess through the
pictures of the CPU and the chipsets installed they concluded in their  last
response was that no mod to the WGS was neccessary, just "Turn-in the BOLT 6
revs, no more. "  I took that as clockwise, and did so to the tune of 5-1/2
turns until the diaphram was getting torn at one of the screw holes... No
change in performance, maybe worse (thought the weather has been warmer..).
I e-mailed them this result and asked for clarification of the "Turn-in"
direction  (seems like counter-clockwise would compress the
spring..simulating a stronger spring(?) which has been indicated in past
archives as a necessity when chipping....any help here?  Last thing I want
to do is hurt anything.  Been a couple of weeks and no response from IA
though they are probably worn-out from shadetree mechanics coming at them
from all over - for any and all projects.
This car has recieved most every consideration for proper maintainence,
preventative maintainence, sensible upgrades (EUROS, IC Lights, some
suspension, Samcos, etc.) , plus some restoration such as a complete new
headliner. It is my 4th Audi, of many in my family (where they really make
sense, Colorado, Minnesota, Northwest...) and has been pretty much a spare
car for the past year and is now getting back into daily use (wife, giving
up '97 A6 to daughter whom will NEVER be allowed to drive my baby much less
ever understand a 5-speed) and I would really like to get this last puzzle
(well, nearly last) resolved.

All input appreciated and it is clear that without the selfless
contributions from this group I would not be able to still enjoy this car
and as much as I do.

hi keith,

from my documented boost issues - both with my friend's IA3+ and my 034
stage I - the following culprits were the cause of the 1.4 bar max. my car
did NOT stumble though - always perfectly smooth (knock on burled walnut ;-)

1. replaced the waste gate frequency valve (WGFV). i recommend the 034 N75H
2. faulty ground wires to the ecu. - talk to dan eckerman at 034. he's the
salesguy, but he's ask nate who worked on my car, what exactly goes bad with
the old ground wires. i assume corrosion.
3. various boost and vacuum, hoses. if the car is stumbling - that could
also be a symptom of a boost leak.

the interesting thing about the IA3+ is it still reads 1.8 bar on the stock
gauge - despite the 3.0 VMAP sensor. it should read lower). with the 034
stage 1 (3.0 bar sensor as well), i will MAYBE hit 1.5 bar - but the turbo
is boosting pretty much the same as the IA3+. this was verified with an
aftermarket boost gauge by 034.

the IA3+ on my car dynoed about 228HP/258 torque to the wheels. with the
dyno tuned 034 stage I - the results were 233HP/260 torque to the wheels
with a MUCH better power curve. especially up top.

see ya,
Robby
