First log question about gm 3 bar

Hey all

Just got my ecu+ installed with the GM 3bar. I did a quick 3rd gear pull but only got to about 6k. Anyway the output from my MAP was hopping between 19.3 and 17.7. Kinda like a saw tooth wave. I this normal? My boost gauge was around 1.5 bar.

Thanks

Well, it depends on the boost source your tapping off.. If its a source shared by an electronic boost controller then its possible..

If you can "feel" it when it does that, then check your plugs it may be misfiring..
