Hi I get mine end of October and after running in intend to do a dyno before and after fitting the spider.
I was at the motorsport oufit that dyno'd the Kuga yesterday collecting my race car (as I'm racing at the Nurburgring this weekend) They told me the Kuga came to them as standard which should have been around 134 bhp, when they dyno'd it stock it came out at 143 bhp so thats 6.7% up on standard, they fitted a green panel filter which then took it up to 149 bhp. They then fitted the spider (literally 2 minutes as it plugs into the vehicles original connectors) The owner then drove approx 1000 miles so the spider could learn his driving style, he then brought it back and it was re dyno'd at 183 bhp.
This means the panel filter gave + 6bhp and the Spider gave +34 bhp. If you add the + 34 bhp to the stock 134 bhp you get a total of 168 bhp which is in line with spiders website claims. the 6 bhp given by ther panel filter came at a cost of £45 (Trade)
This is the exact mods I will be doing to mine, so an extra 45 bhp and heaps more torque comes to a total of £420 good value I think, and also another benefit is you can take it off before the service so if the dealer flashes the ECU you don't have to re programme, just refit the spider when you get it back, much easier than a handheld programmer crashing whilst re programming and messing up your ECU maps completely.
Will keep you posted on developments, asked the tuner if I could get the owners permission to publish and he says he will ask him but he is away on holiday until the end of the month.
