Got a 2012 Cruze 1.4T auto that just cannot manage to hit my desired boost level. Got something still limiting me after several changes to the tune that should have eliminated anything holding me back now from reaching my desired boost. Got my max boost limit set to 240 kpa so nothing too crazy high, roughly 20 psi, so nothing crazy high I'm asking for. Anyways been through and made the changes necessary to this point that are supposedly the boost limiting factors in these operating systems with these particular cars. Based off a couple of the larger general Cruze tuning threads from a couple few years ago driver demand 100% row is set to 300, torque limiting tables under tq mgmt set to around 300 each one, knock airmass set to 2.00, pressure delta factor set to 2.00, overspeed limit min set to 2.00, pressure ratio max table set to 3.00. Basically everything that Chris had mentioned in this thread http://www.hptuners.com/forum/showth...-Tuning/page11 that "should" eliminate any limiting.
Anyone else run into this on the Cruze? Posting from my phone at the moment so cannot post my tune file at this immediate time but surely can later. This isn't a throttle closing issue, that's staying wide open throughout an entire wot run. Just driving me nuts why I can't get to my desired boost. I'm hitting up around the 220ish kpa range so still missing 3 psi roughly.
Thanks in advance to any input on this!
