turbo tips, 3sgte 101 Options

[Malhar95]

i just purchased a celica with a st185 swap from decker here on the forums. reading up everything now.
any suggestions or tips for what not to-do's or anyhting other helpful links would be appreciated.

so for what i know, 2nd gen 3sgte which reads about 12-13 on the boost gauge. driving it back to houston from kansas city the air/fuel ratio was jumping crazy between lean and rich the whole time. not sure if defected meter or something else.
also realized that the top mount intercooler isnt a good idea but im still reading and researching on that. And also trying to find how to get a BOV on the setup(i want that "patishh" sound lol)
keep in mind that this will be my first turboed/swapped car, so im pretty much the dumbest of dumbest...dont really know much. any tips and suggestions work.
