Glenn is a retard.....sadly he does know how to tune AEM from what i remember he tuned pauls car who was pretty much untouchable back in the day.... but as far as anything else having him build or sell you parts i wouldn't advice anyone to go to him EVER!!! I had a friend call him when he went on his whole ill tune anyone who has a martin maf tune for 100$ just to prove him wrong and when my buddy called GLENN told him that in order for him to get the deal and tune he would need some "SPECIAL" injectors from new zealand that only he sold since hes the distributor in order to produce the gains that he needed to prove rom tunes wrong. That alone should tell you that this guy is a dumbass, way to make a good impression on a new customer and keeping your so called "word" on that tuning special and losing out on money everyone should save yourself some time and just go to alpha at induction performance hes the only tuner in tampa that is worth anything these days.
