Just wanted some input on what i should do next, i have an s100/p28 sitting in my room, but i was told that i need to switch my thermostat to stock (from the mugen) for them to tune it properly. but thats besides the point, it just gotme thinking hehe. Just wanted to know what i should do next before getting it tuned?

major things done are aem cai, full exhaust /w test pipe, prospeed header, skunk2 stg2 cams, crower valvetrain.

and yes in the future i will be upping the compression

 

Do a leak down test to make sure everything is okay. I don't know if Hondata can make adjustments for the Mugen thermostat and fan switch or not. Neptune can. Ask some people who have Hondata or send them an e mail.

 

I havnt hear dof neptune before.. is it similar to hondata?
