    -------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.

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

    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

    I've clocked 7500km still the same level of oil at the stick �� Looks like the mod has worked.

    ==============O2Pilot Update===============

    8500km so far, my oil change is overdue The same level at the stick.
    The mod has worked 100%, yesterday i made some extreme pulls, the car was under full load for 7-8 runs 0-200km/h despite i am late at oil change the engine didnt make any ticking noises nor the level dropped.

    ==============Ignition and AFR Update===============

    Yesterday i used a different gas brand for the first time, to eliminate the cause of fuel. To my surprise the logger showed better ignition results, it would run 28 degree tops sometimes would drop 3-4 degrees but would come back to the top value, previously it used to run 26-27 tops and then 21-22 and couldn't increase the value. My good friend Akaki at the ETS (Link for the tuning shop: https://www.facebook.com/Euro-Tuning...15584733591996) retuned my AFR, previously the car would run 12.5 and after some pulls it would stabilize at 12 untill 6000rpm and 11.5-11.9 past 6000rpm until 7000rpm, no matter what we did with the tune values would not change, this time things changed, the car runs at a stable range of 13.0-13.5, the power is felt past 5500rpm, better acceleration. Next week I will run some tests for the timing values now that i have a stable and perfect AFR for maximum HP.

    Please note that better ignition probably resulted from different fuel because my friend only changed the fuel maps but better and stable AFR has resulted from my friend tuning the car properly, it has nothing to do with fuel.
