Ok, from My last thread i have decided I have to spend the extra money and do it right so again, heres what I am working with.... 98 b18b 00 b18b head 91 Integra LS ECU (OBD1) 91 LS Wire Harness T3/T04e with 57 trim wheel and .50, .63 A/R Tial 38mm Wastegate HKS BOV Custom Equal legth manifold with Downpipe Spearco Front mount And for the fuel... RC 550cc Injectors AEM Fuel Rail Walbro 255gph fuel pump Now My question is, if I buy the hondata, with the 550cc injectors, can I run ok at a light 7 psi of boost, or will i still be WAY rich? Can the Hondata tune that well to handel the 550's? I am not going to ditch the 550's because I will later build my bottom end and dont want to buy 2 sets of injectors (450's then 550's). From ya'lls help I have ditched the SAFC2 idea, and decided to spend more money on the Handata. HELP! I have money burning a hole in my pocet and need good fuel managment! Thanks for any help!
