there was tuning done and more fuel was needed because air/fuel was lean. if i had a scanner i would publish for all to show or see the figures written in sc mag about the 2002 & 2003 sydney holden v ford day as i won both dyno comps and the only differnece was the plenum and tune. afr's were always 12.0:1 on the dot thats is how i liked it. but on the dyno day of 2003 they dropped to around 11 showing just how much more potential the plenums have. but cant prove that, just go by what i have as mentioned previously.

Petros anything you wrote got discredited with the microtech bit..... they are so bad , do you tune ECU's???? ISLEEP, your plenums sound interesting, i see VPW are stocking them now?] as well as the 6boost manifolds cheers darren Some original photos have not been recovered yet.

they sure are and i have had discussions with another distributor today. watch out for some marketing coming up soon. i am currently developing some for 13b's with some assistance in testing from a workshop in melb hopefully and then the xr6t's are going to get a work out with a workshop in sydney already having supplied a test car.

Well done, i have respect for people like yourself and kyle with some initiative,good luck cheers darren

thanks darren, wouldn't mind throwing one on your (mrs) car for a quick comparison Some original photos have not been recovered yet.
