Vehicle has 3 bar map sensors fitted, 2.72 upper and ati larger lower pullies, id 1050x, 93 octane, long tube headers, catless, manic clutch, should be making 16psi as advertised.
I am experiencing boost cut at 200kpa range, esp doing its job earlier in the pull then the actual problem area shown later in the log. boost jitters all over the place, pratio is steady, map sensor wildly swinging. Is there a limiter I am missing? I have tried over and over to remedy this, traction control off, esp off, and getting the same result.
Although not logged this time, the SC bypass voltage stays put at 0v during the wot pull and the map value jitter.
I did not have this issue previously when the car had a 2.85 upper pulley and made max 198kpa boost. This move above 200kpa is what has me scratching my head. Any ideas or something I may be blind to in the log?
