you will definately need bigger injectors and some sort of fuem management and make sure you get it dyno tunes before you drive it. but remember your car never felt so fast until right before it blows up

 

You can drive the car with a basemap on the ECU. You can romp on it as well as long as everything on the basemap is set correctly. A bunch of people on here ran their cars on a basemap before having it professionally tuned. I also think 2GR84U street tuned his A/F by himself.

 

i ran my car on a base all summer and no probs, beat the shit outta it too

 

i turboed mine and it ran like poo until i got it tuned. it was running so lean it would barely move
