Alright, I know practically nothing about tuning. With that in mind, here is my question. I bought a fuel pressure regulator. I have i/h/e currently. I purchased crower 403's. I'd love to have the 403's put in, but I can't afford a hondata unit and the dyno tuning to go along with it. Can I use the fpr to tune and be safe? I don't want to hurt my car at all. I know I won't get the best hp numbers with just the fpr, but if i get some gain i'll be happy. I just want to know if the fpr can keep my car running safe enough with the 403's. Thanks

 

Can someone offer any advice? Anyone have any experience with this situation?

 

since you really arn't going to make much power with that setup anyway you'll be fine. Actually since the stock honda fuel maps are a little conservative you might be close to target A/F's with that. A tune would be good though for the best power possible through ignition timing
