@ipstuning: Customer's GTS-R wasn't right. We pulled the file — and it showed. Too much boost, wrong pulley combo, stock exhaust doing it no favours. We're fixing it the right way. If your GM isn't right, we'll find out why. 🌟 15 years of tuning experience - 🔧 Custom fab / Engine Builds / Tuning / Wiring 🚘 Drift / Drag / Roll Racing / GM specialists 📍 15 Wetherill St S, Lidcombe NSW 📞 0436 465 186
