My 60ft was 1.66 and also had hefty slip with the BTR into 3rd gear so <11.2 is there no worries. Has gone a best of 126.5mph which was last meeting with a 1.96 60ft for a 11.66 ET....I think the 340rwkw tune has a 10 in it theoretically:) Car is tuned by Heinrich Performance Tuning and is all stock BA even stall.
