Hi guys I'm having trouble with the two for achievements for the 360 version. 5,4,3,2 mach 1! get 50 seconds of airtime in any ford car. Now I have tried this with the ford Shelby and the ford gt. I have done a jump which gives 2 seconds of air time 50 time's in both cars. And the achievement still wont pop!!! Same go's for the deep down, you know you want to achievement. Drive 50 cumulative minutes in any ford car then enter a garage. Again done this with the ford Shelby both racer and cop car and the ford gt. It still wont pop the achievement. Have any of you guys got this two achievements? And if so how the hell did you do it?? Thanks in advance..
