might be limited for room between the thottle body and strut tower for an airbox?
with my quad throttle bodies i only have those ram sox,maf or map sensors arent a necessity if you haved the right ecu. my motec only used ambient air temp, lambda, coolant temp,crank and cam angle and all efficiency calculations were made/adjusted by a combination of lambda value and throttle position, no actual intake pressure sensor. but hey mine are quad throttle bodies and laptop programmable expensive ecu, all of which are good systems,(hyundai, megaquirt, custom throttle bodies. id stay with the hyundai stuff to keep costs as low as possible
