I was running 100 octane. My supercharger is in perfect condition. No evidence of belt slippage. AFR's were a bit lean stacked but not too bad. Bigger injectors, more air and tune seem to be the next step for me after some suspension work.

Thats a leak. Same problem for me. You are building pressure in 3rd and a lot more in 4th.
Another problem is the heat, but not in 3rd gear. Must be a leak somewhere. I bet.
Now I have glued together almost everything. And it works. Knock on wood.
Lets move on to next level on our cars. We, me and my friend, is building Top Mounted Intercooler on a SL 55 AMG. 77 mm S/C Pulley and 190 mm Crank Pulley, and Headers unt so weiter. They will fit our cars. SRT6/SLK32. If the IAT is good, that will be the next step for me. I need that thing. I have pictures on the progress , but how to show you ?
