BenDoCo I'm getten too old for this s**t Bronze Donating Members 4,509 Member For: 12y 2m 29d Gender: Male Location: A big bridge over a river in South Australia Posted 27/07/15 05:12 AM Share Posted 27/07/15 05:12 AM (edited) Was going to suggest a smoke test.... I don't know if my tuners dyno is a high or low power reader or what but to me, it doesn't matter coz as long as I know its getting the correct amount of fuel with the right spark I'm happy. My brief to the tuner was the total opposite to what it sounds like your after. I don't want a tyrefryer so my dyno printout looks more like an 82 was fitted. Boost comes on a tad slower, holds up high for a while b4 dropping off and torque was limited to protect the trans..... didn't help my half shaft though hehehe. Wondering if there's something else going on with your tune coz mine is incredible all the way through the revs Edited 27/07/15 05:14 AM by BenDoCo 1 Link to comment https://www.fordxr6turbo.com/forum/topic/90901-swapping-from-gtx3576-to-gtx3582/page/3/#findComment-1555660 Share on other sites More sharing options...

Pretty sure his only made 18psi as well and the difference between the car is his is manual with cams, mine is auto with standard cams. This is all same workshop / dyno.... They never tried to make any more power in his car because they didnt wanna push the engine and it was getting a bigger setup anyway. I could try the smoke test but honestly the car runs and idles great, never hunts or does anything to make me think it has an issue leak a boost leak.
