    -------UPDATE---------

    Today i installed the supersprint muffler, it is a fine piece of art :D The sound for me is pretty much the same as the ZHP but friends tell me it is more aggresive :D IDK. Check out my flickr account for pictures.

    Looks very good. Thinking this will be the muffler for the ZHP I eventually get.

    Greetings long time no update. I've been trying to solve the problem that i've been having since last 2 months, when racing timing is lowered about 3-4 degrees, 5200/5500/5800/6000 RPMS only. I have changed MAF, Knock Sensors, Sparks but no change.

    ===========UPDATE============

    I still haven't figured out what the problem is, i took the DME off to check it and had some oil in the wire where it connects onto the DME, i cleaned it but no change. The thing that i observed is that when i race for the first time the ignition is close to 29-30 degrees at max rpm, after some racing it goes back to 21-22 which is a serious drop in hp. For the moment i have postponed the matter and did the O2Pilot Mod as i have been experiencing some oil burn, around 3-5 litres per 8000 km. I will be observing to see if oil burning changes, if not then i will look for new engine block and rebuilt it on a M52TU oil ring. After i solve the oil problem i will continue to investigate on the ignition problem, i will be tuning the car without the MAF on my own and will let you know the results.

    I ran mafless the ignition results were better but had some drops but far less than with MAF, the only drawback was that it ran 26-27 degrees which is lower that it used to 29-30. To sum up mafless is not the way to go. For the moment i am observing the oil level and don't have time to far investigate into ignition. As soon as i find the time i will check coil ignition, DME, Camshaft sensors
