I'm on my 4th engine!!!
New engine builder says a stock computer cant supply the tune required to put the info engine air, fuel etc.
I'm not a racer but just want a fast car. Need some serious help after this engine is built.
PLEASE any help is welcomed.
Who's doing your engine building? Who's doing your tuning? If they are both the same person and this is the 4th time, it'd better be the 3rd free one. Engine builders blame tuners, tuners blame engine builders.
There are some limits with the stock PCMs, but for the most part what your doing should be a problem for a "professional". I'd like more info and background please.
