I figured I would ask just to see what others are seeing. My sled I put one on when it was bone stock just to get and idea what it ran before I started throwin some parts at it.
Stock
Idle 14.3-14.9
Mid 15-17.4
Full throttle 14.5-15.0
Before everyone jumps on the band wagon about sensor placement and type of gauge I will mention I have tried all 3 locations, by the temp sensor, pipe neck, and the can. They all read the same, also I use a Dynojet Wideband commander for the ability to log. From what I see and also what most wideband manufactures say are readings are not correct due to undburned full and air in the exhaust, I have found if I even try to go as low as 13.2 under full throttle it is pig rich and alot slower than stock.
Now I added a SLP pipe set AFR numbers are very similiar to stock. I tried to fatten up the mid and top end just to see if there was anything left on the table. Got the mid range down to 14.5-7 and its a little blubbery, top end is at 13.2-5 And I get spanked by a stock 08M8 on long climbs. So I pulled my fuel box off just to see and sled ran way better again AFR is around 14.5-9.
So what I'm getting at is everyone else seeing the same thing or is it just my setup? I put one of these on because I didnt want to F with reading plugs and just wanted to ride. I think if your tuning by a wideband on a N/A sled and aiming for high 12's and low 13's your leaving alot on the table as far performance is considered, just wondering what everyone else's thoughts are?
