Well i sent my computer away and had the VATS removed and a custom tune and the car is slower,I think it is too lean and the shift points are higher and was wondering if you guys think that could cause the car to be slower.Last year the slowest the car would run was 13.2 in the heat but after the tune the best i can get is 13.4 and some runs are even slower.The car was very consistant last year and most runs in good air ranged from 13.0-12.9.Using my scanmaster the 02 voltage is much lower than it use to be and it seems to have a small miss in the high rpm which it did not have before the tune.Also the VATS is still causing me problems and i emailed the guy who did the tune and he says he programmed it out and that i may need to remove something from the VATS but he didn't tell me what to remove,does anyone know what he means?
