but the black smoke i rich

 

about how much would it cost for a tune?

how do i check the fuel regulator ? and what am i looking for?

how do i check the injectors? and what am i looking for..??

 

most shops charge 100 an hour, do you have some kind of after market fuel controller, safc, or such

 

no it has no controllers...and what do they do and tune.. ballpark estimate of how many hours it normally takes..

 

well you need some way to pull fuel from it so you need something like an safc, it shouldnt take them too long took a shop an hour to tune my cousins srt4 with big turbo. but he has an safc to pull fuel.

 

when they tune it they adjust the fueling for the car, and some itmes timing. you could also probabley get a rom tune but i dont know how much that cost or if it can pull fuel.

 

alright thanks, any shop u would suggest.? phone number?

 

Check your spark plugs and gap them to .030 and pressure check for boost leaks first. Boost will blow the spark out on bad or high gap plugs. Small boost leaks at high psi can open and cause breaking up. $650 for a rom tune at XAT Racing. A ball bearing t28 @13 psi can put you past the 250hp mark; where you start to need some kind of tuning, injector upgrade, as well as mass air flow sensor upgrade like a z32 mafs. You cant run that much boost safely without those mods. As for the intermittent smoke, that could be turbo, head gasket, etc. Get it checked out.

 

SAFC or similar piggy back can be tuned by an experienced tuner (such as XAT) in an hour or two usually.

 

check out xat, s&r performance, race related they all do dyno tuneing.
