No knowledge of what's gone into the car?

There is loads of the kit listed???
As for no dyno, ok the print out themselves aren't actually shown, but, there are videos of it on the dyno in different states of tune:

I wasn't suggesting anyone buy it at list price without seeing the invoices for the work

but, if it stacks up, that's a lot of lude for the money.
