Hi folks
I have been looking to get some better performance from my 156 having got rid of the 3ltr GTV.

I don't have lots of cash to spend on mods however. A friend has advised me to avoid a 10-15 bhp chip mod cos' he seems to think I won't actually get 10-15 bhp; he thinks I will probably only get 5 bhp at best. He did suggest the chip with a new cam although that is getting a bit more expensive. So i guess first up, can I gather some opinions on my options? Also, does anyone know if a 2002 156 ts is fitted with knock sensors? Looking to run her on V-power... My friend reckons this is going to be the cheapest way for me to make improvements to performance. Also, any thoughts on "Sprint Booster"? Thanks all in advance.
