I just took my 86 951 out for a little spin since the temp is cool tonight and in 3rd gear and 3rd gear only when I got on it it seemed to have some hesitation as the engine ran up throughthe tach. I didn't have it floored, but it seem to either have a misfire or detonation. I'm stumped because it's in 3rd gear only.

I am running 17 pounds of boost with a Vitesse stage 2 with all the trimmings.

What do you guys think the problem is?

Thanks,
Chris

Do you have a wideband? Good fuel? Clutch? I dunno, mine seems do the same thing when I tried 19psi, backed it down to 17 and problem went away.

I have a turbo cup clutch with 3k on it, 93 octane. Not sure what a wideband is.

Wideband measures your air/fuel ratio
