hi 3rd gen. lovers, im new to your site, but have read some threads from various sites and this is were the knowledge seems to be. Anyway im putting together a 92 trans am convertible and tryng to wrap it up for the powertour at the end of may.
what im looking for is some guideance in injector size and someone to tune my factory ecm.7730(MAP) the car has the follwing list of upgrades: a 4 bolt 355 1 piece block w/ scat internals afr 180 eliminator heads ( the new ones with the LS valves), a lpe 219/219 @.050 with 544" lift with 1.6 rockers, tpis ported big mouth intake with a lpe super ram, and an as&m 54mm throttle body, 255 walbro pump, shorty headers with true 21/4" dual exhaust the car is normally aspirated comp. ratio is around 9.7 and a 9 bolt 3.27 rear with a 5 speed rounds it out. Also im near gainsville fl so the air is good here(near sea level) im not sure if that should be a factor when selecting an injector size? I have people telling me 24lbs is plenty to no less than 30 pounders will due, i dont intend to go to an aftermarket fi control system, but have recieved any diff. opinions on that also. if anybodys got similar setup thats dialed in your help would be much appreciated!
