Out with four new builds this last week, two were set up in Utah and two were installed by the owner, all four ran between 8 and 9 lbs boost and they ran all flawlessly threw the day, with no tuning needed... Owners were all shocked how well they ran and hit 115 to 120km track speeds on stock 163 xm tracks... So get it figured out... They work
None of us had intercooler or w/a and ran good... Never seen once over 100f charge temps even on the longer pulls
