My reply varies but it's based around the same view. "You have a XXX dollar car, you just told me you spent 30K on a build, it runs terrible, you want me to fix it and you're crying poor mouth? You might be in the wrong shop."Originally Posted by Ben Charles

GHuggins,
So, should I still install it?
If so, I have the Bosch 3-bar MAP that came with the magnuson that is on the back of the SC, and I bought a new stock GEN V 1-bar MAP (GM 12711681) for the SCIAP Sensor. But I can't find the table for the GM 12711681 sensor to get the correct offset and Liner settings for it. Do you know the offset and linear for the factory GM 12711681 1-Bar MAP?
You need the background settings fixed, otherwise it's kind of pointless and will put it into what I like to call a "lazy" throttle mode. Email or contact Will_974 on here. He can put all of the background tables including the sciap offset and linear settings in for you and even fix some of the background torque limiters. There's also a smoothing factor and what i assume are expected value tables for it that need to be populated along with a master on/off switch to use those tables. Some of the SC companies are now sending out the blowers with the lt4/lt5 map sensors. If you have one of those setups then all you have to do is wire in the temperature wire to the ecm like an lt4's and activate the supercharger equipped settings in the cal for it to use the pre and post temperature readings. You can have it dyno tuned from that point. Just make sure to tell them it's in the calibration just like an lt4 and to not change that stuff. Since you have a 2650 make sure to let Will know to use the LT5's settings.

What length pushrods did you use for your Johnson lifters? Did you use a pushrod length tool to come up with that number? I'm looking at getting some for my L83 while my heads are off and wondering what to get and how to determine what I need. My pushrods are BTR 7.850' but I am finding out the Johnson 2116LSR's are a bit shorter that stock lifters.
Stock Sucks but IT's reliable!
did you ever get this sorted out? Ive got similar setup with same issues
I ordered a push rod length tool and measured and added the extra preload (.030"). 7.95" is what I came up with.
