What is the stock boot cut off? It has been a long while sence i looked. but from the w-body site it says
"Raised maximum boost fuel/spark cutoff from 9.5psi to 12.5psi."
I am seeing boot cut at ~12psi.... From what i was told by the guy who sold me the car, it did not have a chip in it.... BUT now i am starting to think it does... I am running nothing more then an intake, X-over and downpipe (Gutted Cat).
Is there anyway to tell if the car is chipped
Thanks,
Shane
Max stock boost is at 7psi.
8psi is the cutoff point. 7.5 or so is the stock boost level. If your going by the stock boost guage its brob off. Prob need to be calabrated. Use a aftermarket unit attached to the vacume port or map port.
Stock memcals ususaly have the calabration name on them...AUAF, AZRC...ect attached to them. Most programed chips are non-OE...They'll have an actual industry standard eprom ID...(27c256, 28c256 ect..)..but the best way is to read the chip with a eprom programmer.
So...decited to keep her?
The stock chip cutout on my STE was 9psi. You can stretch it a LOT higher than that for like a half a second (had mine to 13 once, not on purpose though), but it will cut out at 9psi if it is constant. 7psi with a peak of 13 (don't know why that would happen, but it could) and then drop back down to 7 and the cut will never hit.
On my TopGun chip the cut is 13, but it is the same way. I haven't run much more, but I have seen a peak of between 14 & 15 psi for a very short period of time with no problems, but if it is constantly over 13psi, if will hit the cut.

I have an aftermarket gauge. I am seeing 11PSI peak, 10 pretty consistant and 9psi tward redline and when engine is HOT. I am getting some more exhaust work done wed. Hopefully it will help me hold boost up top. but a couple nights ago when it was COLD I watched the guage go to 12psi then instantly hit fuel cut. I assume that indicates that somewhere along the line someone chipped the car?
I was going to sell her but i got most of the bugs worked out failry cheaply. plus i don't want to see someone else driving my car :) don't know if i could handle that :). Besides i have almost $4000 wraped up into the car and it still needs a bumper and paint. No way in hell i will nearly that much out of her. I still need to:
* Solder the Cluster (Check Guages, and Low fuel light come on)
* replace the fuel sender (guage is off by about 1/8+ tank and now sticking), and replace seal around the sending unit to the tank, Leaks..
* get a new keyless entry box. mine is junk.
BTW I walked a new body A4 Audi from a slow roll in my TGP. Then he told me, as i was turning into a gas station to "Get a real car, that thing is a piece of Sh*t!". Pissed me off, so when i chased him down he turned off like a BIATCH! what a puss!
