Hey guys so im a little confused.I finished the H/C/I swap a couple of weeks ago.The fuel pressure guage i got was crap.So i know the pressure is of(its running pretty rich).So i need to ,and want to get the car tuned.So my question is(Not where to go,there is already about 1,000 post on that)but how does it work?By this i mean what do they adjust ,tweak,andvance,ect...Also can they do seperate tunes(on the spray and of the spray) on the same chip?Also when getting it tuned do they do dyno pulls to?Ok know i was expecting to pay roughly around 500$ does this sound about right?Also do these places also fix exaust leaks?Or are they just simply tuning shope?Thanks in advance guys
