QuoteNo no, read the details again, I stated down to 8 psi or less like 6, even 4 psi if the knock is still happening/as the boost is taken down, you have a steady 10 psi so not an issue, especially since you ran some extra 100 octane at the track and still had 10 psi. Move on.

Ok, so when it pulls boost it pulls it down to lower than 10psi...so KR isn't the problem.  When I ran the car at the track that was before I put an additional spring on the wastegate...I could pull the vacuum lines off the turbo and it would only get 10psi because thats all the stronger the spring was...now I can pull it off and hit high amounts of boost, so the wastegate should be able to stay closed enough for more boost...before it couldn't.

The fuel filter has less than 8k on it.  The guy that owned the car before me was having problems with it not running and stalling A LOT...so he put a new fuel filter in it and fixed the problem (thats what he told me anyways), and he only had the car for a couple thousand miles...and the fuel filter looks new, so I'm pretty sure he wasn't lying.  I can't remember for sure but I thought he said something about replacing the fuel pump too, but I'm not sure about that.  But I know at least the filter is pretty new.  

From what I have been told from friends following me is that when I go WOT a cloud of black smoke comes out at first and then goes away. (and I'm pretty sure thats normal)

I have an OBD II scantool that I have to use a laptop for, so I have the laptop and everything...just need the scantool.  I guess I will do a search and see what I can come up with.  I know that will help me more than anything.  I use the OBD II scantool OFTEN, usually at least once a week...I actually used it today, so I'm pretty used to it, just don't have one for OBD I...time to do some looking.

Wait a sec here.... I'm confused about something, Shawn you indicate you are running a BOOST CONTROLLER in addtion to Jeff's TG160 Chip... What good is the boost controller doing for you when boost is regulated by the CHIP? (Fuel cut off at past max boost? I know the TG160 Chip is reprogrammed for higher boost.. So why the need for an additional Boost Controller? Am I missing something here :?:  :?:

Many people run a boost controller because they feel that it will help to max out the boost and "regulate" it better. I have never had a manual boost controller so I can not attest to one...but then I have never had an issue with the stock wastegate controller on any of my vehicles. I am sure Jeff will agree with me that only allowing the stock boost control device is the way to go as he has stated and I have found many times that when you get knock you don't always hear what can be damaging. If you have a manual boost controller and you get a tank of shitty gas you will get damaging knock and never know it until it is too late. Now if you are constantly monitoring knock with a data-logging device and adjust the manual controller to reduce boost...thus reducing knock you will be good. But without a data-monitoring device...then relying on a properly working stock boost controller and knock sensor is the only way to go...IMHO 8)

Well, yes you are missing something, but just because I never said what it was, I am using a boost controller, however the reason for it is probably different than you think.  When I was running the stock chip I was playing around with things to try to get the turbo to spool quicker off the line and to try to get a little more get-up-and-go out of it and figured out a way to modify the stock boost controller to be adjustable, this way I could lower the amount of vacuum going to the wastegate so that I wouldn't get as much of that programmed turbo lag off the line.  It also put the boost up just slightly to 8psi.  It probably wasn't a good idea now that I look back on it, but it seemed to work good (it probably helps that I always run 94 octane on the street), and the car ran pretty good.  However, seeing that I modified the stock boost controller to be adjustable, when I put the chip in it I couldn't just take the boost controller off, because it is the stock boost controller, so I turned it down all the way (back to stock), because I knew that more boost than what the chip gives is stupid.  But when I was getting a low boost condition I turned the boost controller back up as an experiment to see if I could get the boost back to where I thought it should be with the chip (11-12psi)...and I saw no more boost.  So I turned it up all the way (no vacuum, just like pulling the lines off) and still got no more boost.  Pulled the vacuum lines off just to make sure and still no more boost.  So I came to the conclusion my wastegate spring was weak, so I put on a new one and I get more peak boost now, but still the same amount of steady boost, and that is where I am now.

Hopefully that explains it all.

QuoteAND, do a search for scan tools, there are a number of cheap and free ones, most require a laptop, running with either DOS of Windows 95 or 98, some for 2000 or XP but will still run on an older operation system, no speed or awesome laptop needed for these systems so don't sweat that.

I have been looking and I cannot find a scantool for less than about $210.  I was hoping I could find one for like $100 or less.  If you could get me a link or something to one that is like $100 or less that would be awesome.
