Yes I know its the v8 section but seems more of you answering over here vrs the 6 cylinder section plus the guys that know their shit seem to hangout over here more then browsing the smaller engine stuff. I see a lot of people fight this on trucks and corvettes boosted camaros so why not the 3.6tt in the vsport or atsv. I have tried maxing tables or just raising them. I have gone all over the whole tune from one end to the other and either I am missing something or the program is missing a table for this car. It seems no one has an answer for the atsv either as it is the same way and to control boost and torque it just closes the throttle. I am logging torque like 5 ways and can see delivered torque cross over both max engine boost torque and max engine torque and then it closes the throttle to 50-60 percent and never gives it back. On the ats 2.0t it would close for a brief fraction of a second boost would fall and it would go right back to 100 percent this car never gives it back. I have read many different threads on all kinds of cars and nothing has helped yet. So I need help from some one much smarter then myself or someone that has stumbled on it and can share.lol I have found a lot that way but not with this. So here is a current tune and one of the last logs. Car feels good at 50 percent but the brief moment of 100 percent in first it is a raped ape before giving up the throttle.
The other thing is I dont know why but in the car the boost gauge reads 14-17 psi but the way I log my torque I put it in a histogram at rpm and kpa to see where it is for boost and it never shows over 125kpa? I do the same thing on my tahoe with a lsa blower on 12-14 lbs and it reads 190kpa the same table using the same log setup so why is the caddy only showing 125 kpa in the log? Just baffled all over on this car. two logs and a tune...Thank You
