OK, so I put in the stinger kit on my suburban, but I haven't yet touched the pump.
Seems to breath better, but not a lot more power to speak of. The weird thing is that it accelerates better with less throttle rather than more--more throttle makes more noise and higher EGT's (seem to peak out about 900F) but not much else. About 1/3 throttle seems to get the best acceleration at the moment.
Does this indicate too lean of a mixture? The Banks paperwork says to turn up the pump 1/8 turn, but is there a better/more accurate way to "tune" the pump? For instance, can I take it to a Stanadyne dealer and have them hook it up to an exhaust analyzer and tune the pump setting more accurately that way?
Or is it just hit or miss thing to fiddle with the pump until it seems "right"?
TIA,
