I just picked up a stock 89 T2. The stock exhaust is leaking a bit, kind of driving me nuts. I ordered the motoria exhaust through the groupbuy here on the board. Once i install the exhaust, I shouldn't have any problems with fueling right? I just want to make sure that with the free'ed up exhaust, the engine wont run into a lean condition, since it'll be making more power. I'm leaving everything stock for now. eventually i'll get some 720's, a safc, and up it to 12psi, or whenever rtek comes out their 2.0 chip for the S5. I need the car to be reliable since i drive over 80 miles a day to and from work.

Thanks!

IT will all depend on the boost levels you see after you bolt on the exhaust. That will be the primary driver of wether or not you need more fuel.

 

If I leave the wastegate alone, technically the boost shouldn't change right? I dont plan on upping the boost at all yet. not until i get all the other stuff to make it safe. I just wasn't sure if the AFM was doing any sort of auto tuning while under boost.

Thanks!
