Just got this reply off a local place.
' Thanks for your enquiry yes I am aware of these 2 tuning company's but both these company's are offering what is called Generic mapping meaning they will take a file that has been used before and upload onto your ecu, the problem is there are no 2 engines that are identical so the job you have done is never at its full potential,
secondly they cannot tell you what your BHP or Torque is as standard are you 10BHP up or down before you start?
as there will be no dyno facility to compare against.
Do these company's have any form of checking for faults or codes prior to carrying out tuning?
Also the figures that Celtic tuning are quoting for the Torque improvement are in my opinion way high, there is no way a standard production clutch can take a further 82lbft over standard without suffering from clutch slip maybe not that day but within weeks that clutch will be US.
We can offer you a full custom mapping session on the dyno with all graphs before and after showing areas of improvement including diagnostic checks at a cost of £385.00 fully inclusive.
I would expect BHP to be lifted by 35BHP over standard and Torque improvements of 50-55 LBFT
If you would like any further information or would like to make a booking one of our sales team will be happy to help'
Does this sound about right or? im trying look at all the different things i need to lol.
