I agree with PDT, I had a custom remap on my 993 and it was excellent, the key factors that made it excellent were:
1) The mapper, wayne schofield - chip wizards in rochdale - has an excellent reputataion in porsche circles - what rep does your £300 guy have?
2) At this time of year (and for the previous 3/4 months) no chance of using him as he is busy mapping GT3 cup cars and the like for race teams - his shop always has a couple of very interesting, expensive and serious cars in it - what cars is your £300 guy working on?
3) He has his own rolling road facilities, or if he comes to you, he books a local rr for the day and he only maps the car on the rr looking at the effect changes have on the various parameters in live rr time - what facilities does your £300 man have?
4) It takes him prety much all day and he is a real perfectionist, how long does your £300 man take?
5) I askd him to tweak my idle via the map, (had lwf stalling issues) which he did as he knows the code, can your £300 man accomodate such requests, i.e. he really does know the code
6) Finally you get a power graph print out and he keeps a copy of your std and new map in case you want original back.
How much £500 plus vat 1.5 yrs ago. Bargain! Keep thinking of going to him to see what he can do with my k03 gti, but don't know how well he knows the mkV GTI code.
Oh the result, with engine mods - cams, exhaust and high flow heads and bigger valves, (which another tuner fitted, wayne was just optimising) the car went from 275hp to 330hp on a non turbo car, impressive!
Anyway 6 simple questions to ask your tuner when it is a custom coded remap to check out oif he is any good or not
, btw revo compared to above is not custom coded, but i would agree is more custom (and hence can run more power as more optimised) than std remap such as the superchips map I am running. HTH John
