Grey Area Performance

"Sam was great… tuned my Ls swapped f100. Good pricing very knowledgeable and got it running in tip top shape. Exceeded my expectations with the HP numbers he was able to get out of it. Highly recommend"

"Sam's the man, man.. Let me use his dyno to tune my 09 P71 through Marty Ochs of Goargia.. Sam also installed my FTI 3,200 stall converter n checked my brakes.. Definitely returning when more mods n dyno runs are needed or wanted.. P71 Mods: 309rwhp 321rwtrq - Maximizer's longtube headers.. - TFS 38CC heads.. - MHS TFS stage 3 n/a cams.. - 25% UDP excluding alternator pulley.. - Ford Racing 8.8 3.73 rear end LSD.. - FTI 3,200 stall converter.. And last but not least, an air freshener..lol jk.. So give Sam a call.. They can pretty much do it all.. Many old skools in his shop, including custom builds.."

"Fixed issue created by another shop, (did not torque harmonic balancer correctly and bolt came out causing damage) Got us in and out quickly and were lower cost then others. Great guys!"

"Sam and his team are knowledgeable about all motor types with the expertise to guide you into the right choices for you car/truck's performance. I was happy with their service and will return for more work to my truck."

"GAP took care of my truck and got me back on the road quick. Very fair pricing, and Sam and his team were very helpful. Thank you!!!"
