I have an SC400 with a few mods, such as S&S headers, 2.25 inch exhaust from the headers back, intake.
I have the same parts lying around in the garage... how do you like it? Any significant gains or anything?
Any word would be appreciated, thanks.

Sure, you can use the chart and select the correct jets as a starting point, and we do that... and usually find that some fine tuning is in order, even as low as on a 75 shot.
A $275 wideband is far cheaper than a motor. Dropping fuel pressure, a clogged line, or too high of bottle pressure would all be caught by a wideband and a responsible driver.

Dropping pressure will be seen with a fuel gauge, too high of bottle pressure will be seen with a nitrous gauge...Originally Posted by qksl2
I disagree. Everytime we install a wet kit, we either put it on the dyno or install a wideband. We typically either see a horsepower increase or a safety net that we can rely on.Sure, you can use the chart and select the correct jets as a starting point, and we do that... and usually find that some fine tuning is in order, even as low as on a 75 shot.

I had an air fuel gauge on my setup and it really seemed like overkill since I wasnt doing anything crazy. I agree with you that obviously an air fuel gauge can proove to be critical in most situations.....but in a situation like this, I dont think so.
Ive had numerous sub 11 sec cars, runnig zeitroniks wideband on each one. I know the importance of a wideband....but without some way of tuning the car like an AFC at the mere least, it proves a pointless and an unnecessary mod for this level of modification.

Does anyone know if I were to run 75-125 shot would I need bigger injectors or a new fuel pump?
