I had a BBK fpr on my 90, I didn't have any trouble with it.

Turn it down to 34-38 psi and go.

I can only turn it down to about 42, it wont go down anymore. Ive heard of this issue before with them.

did you take the vac line off when adjusting it?

86 newbie

Yea, i put the stock one back on and still have the same issues. When at idle and cruise it misses bad but once you floor it, it wakes right up and doesnt miss at all

86 newbie

Ok so wow i feel like a f-ing retard. I was looking over everything and i noticed that the vacuum hose to the map sensor on the firewall wasnt hooked up. I hooked it up to a vacuum port and the rpms shot streight to 3k it wasnt missing thou and no smoke came out. It sounded pretty healthly but my prob now is that its stuck at 3k rpms. Is it cause the cam is so much bigger so the computer is reading less vacuum?

if you don't have a maf conversion, the oem speed density will not run right as load calculations/fuel map will be skewed as map is a contributor for such based on vaccum readings as for idle, perform base idle reset.

86 newbie

Yea i cant even get it to base idle reset...i just think that cam is too big. I might put the stock one back in and go from there

why not just do a maf conversion??

Yea just do a MAF conversion. Simple and youll be much happier
