I recently installed a BBK CAI w/Brenspeed SCT tune and decided to put it to the test................... I started from a dead stop and launched it (traction control off). Much to my surprise there was NO wheel hop - just screeching tires and a quick redline of the engine (6,200 before I knew it) - SWEET! I had a 2005 Mustang GT hardtop with a CAI and tune and the wheel hop was terrible (with stock 3.55 and 4.10 gears - both bad)! Is there something different on the vert other than the two under frame rails that are there for added rigidity? Maybe they make the difference?
