engine tune

I have an '03 ZX3 zetec if I install a JRSC BBK will I need to have the engine dyno tuned for reliability? Also will my stock automatic hold up to the power? I searched for awhile and could not find anything. Thanks for any help.

it should hold up for a while the stock atx the bbk will put more strain on it but the plain jrsc will be nice for an atx car.


they have black box tuning which is more like a bullshit tune. nobody has had a problem with the bullshit blackbox but everyone knows if you get real tuning you will get better #'s and your car will run better.

Do you already have the JRSC on the car and want to upgrade to the BBK? Then I would suggest a re-tune.

No I do not have the JRSC kit yet, I have just been reading how people do not like the black box and say it can harm the engine is this true?
