I have an r32 gts-t , i just bought the car 2 weeks ago and my first test drive on it was sweet. but once i actually got the car it just seemed really sluggish especiialy at low revs and first and 2nd gear.... i was told the mods on the car wasa gt28 turbo, fuel regulator, mines computer, boost controller, high boost set on 18-20 psi.....someimtes when i give it heaps the car jerks around alot and is very sluggin in low revs as in very slow... i was told its the mines computer coz it runs very rich fuel and is designed for japanese fuel only....does anyone know how to help me please?
