Hi,
    im using the qlcc well was.. my 4000 with mc  had 1 bad rod bearing then 
the crank bearings came with it... dumb mechanic who dint do his job right 
(there were markings on the rods so it's been pulled apart anyways im 
replacing the cank and bearings..) i have already a blow by valve installed 
because i use a 4000 airbox and there's no room for that valve that opens 
when you lift off the gas dont remeber its name... i know lots had problem 
with it getting stuck open...
Anyways....
I read about a new mod changing the ecu's pressure sensor to accomodate the 
higher pressure...
but don't know anything on how to proceed what sensor should i buy  where do 
i have to install a resistor, if i have to, do i have to modify the chip's 
bin again ?? Would running 2.2bar with the qlcc be too much?At what me 
address is the overboost cutout  what would be the value and does the file 
have a checksum ?Any help on this subject would be apreciated.

Oh and i finally found out what the 1990 qc dancing problem was (when 
running at 30 + the car back end would suddenly go side ways on asphalt  
from time to time... one back end shock was scrap ....but had no sigh of 
leakage  and you could'nt feel it in the car...din't fix antilock but was 
able to take it off the stupid differential lock button was stuck and the 
antilock wouldnt go off.
