See, when you have a car with forced induction, they can develop leaks of sort, some of which bleed off boost. In my case, I was only running 2/3 of the boost I was supposed to (.9-1.0 as opposed to 1.5-1.6) and still trapped 125. Keep in mind, the car EASILY is losing around 50-75whp because of that boost and meth issue. I still ran an 11.6 at that 125mph. Would you post one of your time slips for a comparison?
And just so you can understand physics, 600whp in a 2000lb Honda will trap easily in the 135-145 range. 600whp in a car that is almost double the weight should be around the 130-135 range, easily. Welcome to physics class, how about you go sit in the corner.
