The table details just what sort of performance gains a hot chip can produce. With cars such as the BMW 325i, the most significant gains are in smoothness and upper-gear torque.
Although the figures for the 535i (E34) were spectacularly improved with the chip, the most important benefit was the elimination of two noticeable 'flat spots'
Similarly, the automatic in the VN SS Commodore didn't kick like a mule on every gearchange, the VP Commodore gained excellent mid-range punch and the Porsche lost it's throttle-snatch characteristics.
On figures alone, there were some star performers of the day, including these impressive improvements...
- BMW 535i (E28): 0-100km/h - 2.75 seconds
- BMW 535i (E34): 0-100km/h - 2.5 seconds
- Commodore VP V6: 60-100km/h - 1.8 seconds
- BMW 325i (E36): 60-100km/h - 1.71 seconds
- BMW 535i (E28): 80-120km/h - 2.23 seconds
- Commodore VN SS: 80-120km/h - 3.04 seconds (biggest gain of the day)
Counting the Cost
There is good news and there is more good news in this department.
Typical Powerchip replacements for the average car are a few hundred dollars.
Commodore V6 $340
Commodore V8 $450
High-performance cars which require chips with more complex programming cost a little more - $650 for most BMWs, Porsches etc.
There are no fitting costs.
High performance air filters are a low-cost option which are worthwhile installing together with the new chip. The average cost of a replacement air filter is around $80.
Most manufacturer exhaust systems are more restrictive than necessary. High-performance systems can provide quite
|significant gains, but it is important that they are combined with the right chip.
A good idea is to opt for stainless steel high performance systems - they cost very little more, but usually come with a lifetime guarantee.
There is a generous interpretation of the term 'high-performance exhaust system' so it is difficult to pin down pricing. However basic systems for volume produced cars start from as little as $300.
but the excitement doesn't end there. Future cars may have built-in mini-computers, with plug-in access slots in the dash, or press-button programs on the wheel. Whatever the path of development, hot chips are here to stay. Why not chip-in now?
