[QUOTE="Wajafly, post: 647877, member: 14660"] First of all, thank you to everyone who replied to me with great advises like EFN and GT20v. GT20v, I don't know the cam lift duration but should be around 270 and below maybe? Got no idea and just guessing. The difference is great with P+P. For my Auto, I can say it is faster than standard Waja but NOT good enough to race with any stock GTI or Perdana. However, I am happy with the excellent service and product of MatSpeed. EFN, thanks for the great tuning reference on FPR setting. Yeah... with the hose disconnected and set to 43, my car chokes like hell and dies off. He (the so claimed professional / engineer boss from power bengkel) says it is a normal procedure of tuning that way. Even when I mentioned what his mechanic did, he says it is normal to him. I had that conversation recorded if you guys don't believe me. Well, I suspect my engine dies off firstly because of wrongly adjusted FPR setting, but the mechanic seems to think the sensors might be dirty. So, he disconnected the connectors from boost sensor and took the high pressure air gun and sprayed into the sensors connectors including directly at the sensor while it's being attached. That is where I suspect causes permanent damage to my boost sensor on top of my Intake manifold which after that, my car not able to start again even after FPR has been adjusted correctly... Sigh... what a Power-Bengkel it is... I have so much high hope in them based on their nice sweet talking website... Sigh... I am still filling up my Tribunal Court of Claims forms... Doktahu, I think EFN also mentioned it is about 43.5 PSI for normal Waja. I heard this setting from a friend as well. Funny, I feel good at 43 as well. Maybe a little higher will give better performance? How high is too high? I heard that Waja is running on high compression already. Maybe that's why we run on lower PSI instead? [/QUOTE]
