I had a Freddy intake manifold with my stock RB25 ECU, it ran like stock, stock turbo, stock 98 240sx exhaust, stock injectors etc..made 268whp and 273wtq on 12psi
Thanks for chiming in on this flatrate. That is the consensus that I am getting from other sites as well. The performance shop in town that is the only shop that I know of that is familiar with the RB motors is telling me that the stock ECU wont work with the aftermarket intake plenum. In turn without even offering to do any diagnosis of the problem they are telling me that the only way to fix the problem is to get a stand alone ECU. I just can't give in to this assessment without hearing it from someone more reasonable.
