Ok, i had a look on Reylands website and it says a 605hp engine can be produced for less than most other tuners charge for a 520hp t4 8 inj unit!! Now im not doubting this, nor am i trying to start a bad thread, what im interested in knowing is, say you phoned round a few tuners asking for prices on these specs(or if they are listed as stages or similar to these):

350bhp 380bhp 400bhp 450bhp

What sort of prices would we be looking at????????

Also to include turbo,intercooler,antilag etc......

Thanks.
