hey as the title says, as I anm coming to a stop and press the clutch in or rev the engine and as it idles down it wants to stall. for the record I have recirculating oem bovs. the car is stock, the engine is stock. just put on this greddy single turbo kit and it starts to stall. I question the maf because prior me getting the greddy y pipe inlet, I had made a temporary dual maf adaptor out of plastic and the car ran fine with no stall etc. however as soon as I put the greddy unit on I started seeing such symptoms. swapped the temporary plastic one I made and no problems. I can only guess the recirc portion of the pipe is at a bad angle on the greddy unit. but has anyone else had this issue? My turbo inlet is 3" and I used a 3" to 4" silicone coupler, would that step make an issue for maf reversion?

thanks guys

Have not heard of that before. I was under the assumption that the Y pipe was designed for exactly that reason and was pretty good at it. Have you check for leaks or anything like that getting in between the MAFs and flanges etc?

      Block bump. $400. As above cyl 6 needs bore or sleeve.

      I would think making the argument that the travel is limited by a spring flexing against a spring perch as "the same method". Later on in the document they do state that the spring can't bind on full bump travel and cannot come loose in full rebound travel as well. (which is all very sensible). The laws are actually pretty sensible and reasonable. It's just that the people who enforce and check them don't actually read them or know them accurately. "Oh, coilovers? Instant fail mate. Don't even need to look at it." - Guy who will be instantly reported by me. There is probably merit to people who do get defected for height also get defected for the suspension in that state that allows it. I did never consider the people who are complaining about coilovers being picked on are also running around at 50mm off the floor.

      Ethanol Content Sensor - Always at 11%?

      I think given SAU's knowledge of E85 we can strongly conclude that 10% ethanol in almost any situation is entirely fine. Almost all of the myths against E85 were overblown, let alone E10.

      From your link See bold text, is this referring to damper settings, if so that may a issue for "some" inspectors, I cannot see aftermarket coilovers having the evidence that "must be available that its functional performance is equivalent to the original" Maybe just remove the adjustment knows and hope for the best???? Meh 5.2 Suspension travel In all instances, modifications to a vehicle’s suspension must ensure the integrity of the system and not compromise the ride quality. At least two thirds of the original suspension travel should be maintained in both directions (rebound (i.e. extension) and bump (i.e. compression)), and rebound must be limited by the same method used by the vehicle manufacturer or if this is not practicable due to the nature of the modification, an equivalent method. If an alternative method is used, evidence must be available that its functional performance is equivalent to the original.

      They actually don't - They adhere to VSB14 rules just like Victoria. The rules are against CABIN adjustable height, and it quite clearly states that the height has to be within parameters. I asked the VASS engineer to confirm this when I got my car engineered and they refused to engineer the coilovers because they didn't meet the requirements for requiring engineering. (mine are height adjustable.) People "Not wanting to bother" with "Actually reading/knowing/adhering to the rules" should result in fines and immediately losing the ability to issue blue slips and/or RWC's in Vic.
