Just rolled up to EFI Performance in time to catch Steve finishing up tuning on this LS swapped Foxbody. Strong numbers of around 490whp thru an unlocked converter/automatic. Smoke is just from the car lacking proper PCV system, everything is healthy. #efiperformance #gmtuning #hptuners #tunedbyfrost #mustang #foxbody #lsswap (at EFI Performance LLC)
