don't get an fmu...not tuneable management. don't worry about an adj fpr...stock is fine.
get larger injectors, walbro fuelpump, an obd2-obd1 conversion harness (call mainstream for those 3), a socketed/chipped p28 (i have plenty for you), and come see me over at mainstream in powdersprings for tuning.
feel free to pm me if you have anymore questions.
