No boost gain
I mentioned in another thread about my fiero , I have a 87 fiero gt with a 93 3800sc.
I swapped the sc for a 95 model sc& throttle body. I used the smaller 93 pulley yet I have no more boost than I had with the 93 sc& throttle body. If I put the larger 95 pulley I can reach 5 lbs of boost (getting 9lbs now, same as befor swap)
Could someone give me a few ideas as to what I should look for?
I have a fairly freeflowing exhaust, CAI and that is about all the mods for now.
I did have a small leak where the egr tube went into the sc but I fixed that and nothing else I know of to be a problem. Any help is appreciated.
