sorry dont have any figures for the chips, i only bought them cos they were cheap!! and i fitted them myself, i am pretty happy with the results though especially in 4th and 5th, my car is still pulling really hard on boost much better than before, can you tell me if drilling the r outlet on the boost control valve will my any difference to my car if i am already running with an lbe????

 

Drilling CV might make some difference. I used to have Europroducts Chips which came with the instructions how to drill CV. I didn't do that.
I am also changed to Guru Racings chips.

 

Where's a good place to get a simple, black faced Turbo boost pressure guage and "sending unit" hardware? I'm looking for budget and reasonable quality. Thanks! - Mark

 

ebay,ive seen nice ones for about $40

 

10psi on the LBE will depend on the condition of your WG.

 

Check out this thread on how LBE-opening pressure relates to actual boost-pressure: <a href="http://forums.rennlist.com/cgi-bin/rennforums/ultimatebb.cgi?ubb=get_topic&f=15&t=010253" target="_blank">LBE intalled, getting weird readings </a>

 

Thanks guys for all your help on this matter, its not easy starting modding your 944 turbo when you are starting with little or no experience with turbos but i think i have managed to follow most of the information given, i certainly do not want to blow my car!! i used to have a 1983 10 valve audi quattro turbo but never got involved in any upgrades to that
thanks again
