Did some run's today after I set up the Gtech SS I ordered. I got this unit because it uses gps technology and not a accelerometer. It has good reviews compared to most and is suppost to be very accurate. My past runs with the same condition's and 94 octane were in around 6.2 sec timed on my iphone. Temp 40 degree's 1/4 tank of 91 octane Dry road with no passengers. Consistant 5.7 sec 0-60 and 1/4 mile of 14.4 All of these runs were not on the same stretch of road so I discarded the high and low. 5.59 and 14.26 were the fastest. I did hold the brake a little to try launching at differant rpm's but there was no noticable differances. The high runs were definetly road conditions and torque steer issues.
