I built my car with a turbo setup thanks to this site last fall and been driving around with a hack tune since then from this guy in florida who i forget his name.
but anyway i finally made money enough to take it to get it tuned but i also bought a slightly larger turbo. a T3 off a 300zx compared to my current 14b turbo. but it would take about the same amount of money to switch out the bigger turbo(getting things like a external wastegate).

do you guys think i should just tune it as it is and bigger turbo later or turbo in it now and risk it not running very well until i get it tuned later next month?

 

I would wait and keep the boost low in the meantime

 

wait till you get the bigger turbo on or you will have a improper AFR

 

i decided to tune it first and then build up everything for the bigger turbo and then tune it again;

1. it will be neat to see the differences between the two turbos
2. for the two i would need a waste gate and i don't have the money for that right now.
3. I am frustatrated with a semi-working car.
