LS Swap'd Z/28 at EFI Performance today getting looked over and ready for tuning. #EFIPerformance #z28 #camaro #classic

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)

Just finished some baseline pulls on this gorgeous Roush Stage3 Supercharged Mustang. Owner is thinking of stepping it up to the 700+hp package soon, wanted to know where he was to begin. #flimflamspeed #roushcharged #mustang #s550 #fordmustang #roush #efiperformance (at FlimFlam Speed & Custom Tuning)

I love shiney new parts. Like these CNC ported LS3 heads going on a G8 at EFI Performance. They should flow quite nicely matched with a custom cam and other goodies. Can't wait to hear it fire to life soon. #efiperformance #ls3 #gmperformance #gmtuning

I kinda love how this blower sounds now that EFI Performance has pulley'd it up and added a cog rear setup on this 2010 SLP ZL575 Camaro. Dyno numbers to follow on Monday but it's well over its factory 575hp to the wheels now. #efiperformance #hptuners #gmtuning #camaro #chevy #chevrolet (at EFI Performance LLC)

Steve getting it dialed in at #EFI Performance at 20psi while I do the driving and keep tabs of the important things. Now stepping up the boost a little more... #efiperformance #hptuners #gmtuning #turbocharged #boost #boosted #mustang #foxbody (at EFI Performance LLC)
