Hello all, We've decided to put together a package for those wanting to release more power from their GT86 or BRZ, without going for forced induction The kit contains the following: 'Before' Dyno Run Tuning Developments Manifold (EL or UEL) Tuning Developments Overpipe Gaskets Heat Wrap For 'Downpipe' Section K&N 'Drop In' Replacement Panel Filter Installation ECUTeK License In House Remap On The Dyno £1495.00 inc VAT Website link here This package has been proven to remove the torque dip which plagues these cars, along with making more peak power. The whole curve is stronger, making the driving experience much more enjoyable! The ECUTeK Remap features the excellent RaceROM which gives you 4 switchable maps via the cruise control stalk which can be adjusted whilst on the fly. For those without cruise control we can set this up via the heated rear window button. Net gains are upto 30lb.ft through the mid range and upto 25bhp peak power (based against a 100% factory car). You do not have to have an aftermarket exhaust, this is completely optional. The second CAT can also stay in place if needed. This gives an end result of a car that when cruising, sounds very close to OE sound levels, and has a pleasant bark to it when pressing on through the gears. The gains in torque make it much nicer to drive and give a far more linear delivery. The top dyno graph has the factory second CAT and factory exhaust. The lower dyno graph has a high flow second CAT and an aftermarket exhaust. Above - TD EL Manifold, Full Exhaust & In House ECUTeK Tune (Didn't photo the overlay from before sorry!)
