I heard of Gio heard he does good work but it is tough getting a hold of him plus i heard he deals with obd1 cars. I wanted to try nistune but the only person i found who tunes nistune in fl is in Orlando roughly about 3 1/2 hours away. I went an researched the g18 turbo alittle looks like it might do the job my mechanic was even saying its pretty good but he was suggesting i just use the s15 setup 550 injectors disco potato turbo z32 maf and the get a programmable ecu and fuel pressure regulator and prob some N1 cams
