Bobda, you continue to belittle Angel Tuning, I have not read any negative comment from any of their customers. They are a reputable company, reputable means someone/something that has a good reputation, there have been 2 posts in this thread alone adding to their reputation.
I'm sorry - where do I belittle Angel Tuning??
I was referring to companies who claim power increases from fantasy land. I have no experience of this
company other than they were the first result on ebay for 'ECU remapping'. They claim in one of their pieces of text that 75% gains in torque can be gotten from a remap alone! That's rubbish, if you ask me and totally misleading to the consumer.
Maybe you would like to let us have your personal experience of remapping of non forced induction petrol cars.
A Squadra chip on my old 145 smoothend out the torque curve and slightly increased the power, but it was nowhere near 20% - I'd say 10% max. The same experience has been felt by a riend of mine who had his petrol 320 remapped, a smoothing of the power delivery and a slight increase in pull lower revs.
Also why 'remapping a petrol car is rarely worth it', what else would you suggest to spend £300 on to get greater gain?
That's just the problem, modern engines are tuned efficiently by the manufacturer, especially so manufacturers like Alfa, Honda, BMW et al (as opposed to shoppin cars like Kia and Hyundai) and as such, gains in power are hard to come by.
I'd regret if I'd spent £300 on a remap for a NA petrol car to get 10% more power, then found out that a further 20% can be gotten for the sam procedure on a TD or forced induction petrol engine.
