I'm trying to pin down this belt slippage issue i /think/ i'm still having.
When I romp the pedal from a dead stop, the boost guage jumps to about 11PSI, from a roll about 30+ mph, doing that only gets me about 10ish PSI. In both cases that initial surge is the highest the boost gets and i'm wondering if the possible belt slippage is the reason for that.
I remember BKB (one of the Supercoupe Stang guys) breaking it down for something like 10ish PSI @ 1500, 11 or 12 by 2500 and climbing to 14 or 15 by 5000. Is that more like it?
I gotta belive thats the reason why the EEC isnt switching to open loop when I get on it sometimes, like 50% of the time it will jump to the commanded 12.2ish a/f and you can feel a BIG improvement over the other 50% of the time when with no changes to the tune, it wants to stay at 14.7
I'm thinking that its the slippage that I may be experiencing thats throwing off the load tables.
So in closing i'm just wondering how the boost curve looks on your engines.
thanks
