Update: As SBS wisely noted. This appears a mix of two issues now ..
(1) I switched to pure meth. this apparently with the update tune took the power levels beyond what the non-PP likes. So i am seeing tons of TQ limiters now. stomp on it, and it down shifts, but it freaks out cuts assloads of power, dumps meth, bogs then overpowers. super spazzy.
(2) advancetrac is sticking it to me hard. if the wheels are turned at all, I cannot apply power. In fact it seems when coming out from decent turn it has less power than the non-meth tunes i was running until the wheels straighten out .. then it hits like tyson on a roid rage.
I am unsure what to do now. Brad can/might tune around some of it. But bottom line is i cannot fully utilize the meth and the power it is generating unless i am in a straight line.
I may have to cap the power to get back the control and ability to power out of turns ..
