21st Aug 12 I’ve had the FSR system on my 1.4L Astra GTC for a few weeks now and haven’t stopped smiling yet. The only time the car was “fun” to drive before the box was at around 3krpm in 3rd gear… It’s now just as fun whatever gear I’m in, whatever RPM I’m sitting at – and 3k 3rd gear is just amazing. Coupled with the V3 pedal box I purchased on the same day (which I today changed from Red 2 to Red 3 mode and started smiling all over again) it’s just a different car. I thought the GTC looked quite sporty when I bought it, and even though it’s a smaller sized engine with the DTUK box on it feels as fast as it looks! I can’t recommend it enough. As a bonus it also is very easy to fit and adjust, although I have to confess I haven’t changed the setting (just the map 1-4) since driving home from the DTUK premises in Durham down to North London.
