need advise on tuning or upgrades
 

Hello Jack
I just joined this fourm,I live next to charlotte nc in huntersville nc. I'm wondering were to go next for making more power either in upgrades or tuning, here is a list of some thing I've put on my 86 gn,car runs good best time 12.00 @113 this was with a ta 49 turbo and no posi. Then I just dynoed the car @ 350 hp and 365 tk, with a 60 series turbo,40 lb injectors,kenne bell 70 mm throttle body and upper intake, kenne bell high flow intank pump and kenne bell inline series 230l/b fuel pump, atr 3 in downpipe, kenne bell headers, ram air kiit, 100 lb valve springs,translater plus with extender chip it reads 23/21 for timing ,front mount intercooler from atr,SMC progressive alky system ,scan master and a/f meter guage. added a posi, I'm running 24# boost,50 # fuel press at idle with hose off.scanmaster reads usually 770 to 820 and a/f reads 11.3 with alky on. if alky off sometimes 3-4 retard on scanmaster. wiyh bfg drag radials,2 air bags just seeing were to go to make more power without spending to much money,maybe larger injectors and new chip any help would be appriciated, thanks
