I had Jez remap my 06 G35 (V35 Skyline) back in April and it is by far the best tune I have gotten on a car ever. I picked up just over 17 WHP on a non rev up DE engine with a Takeda intake, Motordyne Iso Thermal Plenum Spacer, Invidia test pipes, and Invidia Gemini true dual exhaust. My throttle is very responsive, my powerband is longer and smoother, and my AFR is tuned perfectly. My mate drove my car and is now bringing his G35 with a vortech supercharger down to Jez so he can get the same awesome service I recieved. +1 for Jez and Horsham Developments!
