Thank you for keeping the res.! Yeah the u-bend delte is what gave you that power increase, zzp says its about 15 hp but idk if that's right I dont think it's quite THAT much. Youre next mod should DEFINATLEY be an FWI and a 180 thermostat before you get a PCM. Not only are those first two good, cheap mods but any off the shelf pcm will be set up for those mods. My opinion on the PCM would be overkill, everyone's will be different alot will say intense, but I've never heard of an overkill frying a motor intense has. Just whatever you do STAY AWAY from the ZZP pcm if you like your motor!! Good luck with the modding! You should read the safely modding your 3800 thread.
