My buddy slamms is EGT's all the way down the track and the entire 300 ft pull. He hasn't had problems yet........ But he also has several mod's help back that up.
The other day I saw 1200 area and decided that was good enough for me. But also thought the same when I hit 30 psi, next day I wantedt ot see if I could slam the 40 psi guage.
