Got the mustang out on the road tonight. went slow at first checking things (SCT livelink datalogging is just the worst, everytime I try to do a new datalog it freezes the computer and I have to spend 5-10 minutes getting everything hooked back up) and then made a couple small pulls. The car seemed to do really well minus the powersteering pump being beyond angry, time for a replacement.
Later my friend came over who helped me put the time lapse together so we went back out again to get a 3rd gear pull. Its not even funny how much better it drives right now even with the tune being slightly off but still safe. AFR's are really rich still at WOT, can prob lean it out to around 11.3-11.5, right now it hovers between 10.8 and 11.0. Spark is around 18*.
Old custom ground cam is in red, stock cam in blue. IAT's for red were 72*F , IAT's for blue were 50*F measured at the maf at peak rpm. Other main difference included changing the intercooler from a same in/out to an opposite side inlet/outlet which flows better. Runs were made on the same stretch of road, with the same two in the car with the same driver. These numbers aren't meant to be actual dyno numbers, but a fair representation of the change in hp/tq between the two setups. 3rd gear pull, assuming 3550 car weight and 450 passenger weight for both occupants.

Boost comes on so much harder at low rpms, much better for what I was trying to get to. Will try to get the tune ironed out this weekend as when I initially come off the throttle the afr's go pretty lean with no load (so no concern) but still would like to get it set up to where between shifts it sees at most 14.5-15afr instead of 18. Also want to get the afr at WOT back up to around 11.2-11.5 and dial in teh spark timing a bit more in the 4000-4500rpm range where I start to really loose torque.
