I put a manual boost controller on my car and it solved my spikes! I just put it on and got a 8-6-8 boost pattern. Now I just need some more gas so I can get the right boost out of it! Even with the midpipe in it is having no problems. It is quite cool outside also..Damn am I am happy man!

 

nice work man

which method did you use exactly?

Is your boost pattern with the bleed valve or valves wide open?

Please pm me with more info I'm about to do this myself as soon as I figure it out. I have a intake, streetport, and full exhaust on the pettit ecu so my boost is running free right now I need to figure out how to control it effectively like you.

l8a!
