I have a stage 1 sc on a phazer. Having troubles having to keep adjusting the altitude box. Climbing the same hill. I got no response on my first thread. Anyhow took it to my mechanic and he took it out flat landing. Said the exhaust was glowing red when he would have to adjust the box. He thinks that there is too much restriction and the heat is creating the trouble. Con anyone tell me if this could be? Thanks
