true....but the Hartge is nothing more than a smaller pully which is dead easy and a few other minor parts, its too easy to get power out of a forced induction car to compare really.
JCW Cooer S upgrade is a good example, it took 2 prototype Ss before they were put into production to test, and it took them 2 yrs to build a package under factory support.
No local UK tuner has that sort of resources......which is why they do it on a car by car basis......layout of about 30k to develop and test is alot, and in most cases, you only get people calling up, talking and email for about a week on the benefits, estimates, time, costs, then tell you Quote:
"cool, i wont be needing it for a while though"
Ask any tuner how much gyp they have to put up with from prospective clients........and its the same thing day in day out, most jsut dont come back for the serious stuff.
So youd need to do about 10 "kits" minimum, and well...who here HONESTLY will part with about 3.5K for over 200bhp with no gaurantee?
its a tricky business.....and even HUGE tuners like Longman take a while to make such kits.
