unkown problem evox

I own an Evox 2014 GSR the car only have 50k miles on it right now. i have done a cam job on the car by a professional guy ( cam type is GSC S2 with springs and retainers) the head got shimmed correctly and everything was done to specs. We went through one problem which was both mivec solenoids which was done by replacing both of the Solenoids. One problem that we arent able to solve is the car keep bogging/ shooting flams on low RPMs but after 3k RPM the car runs perfect, how ever we thought its fueling problems, we put a new whole fuel OEM hosing with a new fuel OEM pump just for test and the car is still acting weird for some reason which we cant figure out. i started to think its the ECU. the car didnt though any codes for whats so ever, any suggestions please ?

It sounds like you need to refine your tune, not keep replacing hardware. If I were you I'd get someone else to look at your tune and see where you're at. Lot of good places can even work with you remotely - wtftuned.com is a great guy to work with, there are others as well.

the car is on a base map, the car runs fine till it heats up then it starts acting up like crazy. any rpm lower than 3k it will bogg/back fire.

Still say you need a second set of eyes on the tune. All of that behavior is controlled by a tune, it's really best to start there. While you may have a lot of faith in the guy you are working with, it's worth it to get a second set of eyes on it to ensure you are not just throwing parts at a software problem. You don't even have to tell the guy you're doing it But get it checked. There are a lot of awesome e-tuners out there that can help you if you're not local to them.
