HPF xcal tune. QUOTE]
Theres ya mates problem....Jokes!!!,Rob knows his stuff as does the tuner.
kuz,you need to stop shooting peoples qoutes down power/figure wise especially when it comes to Fords,not having a go but its not an area you are familiar with.We(yes I can tune) have people with similar figures with the mods you suggested in your mates FG with around 180rwkw,this dyno is not "happy" so to speak as my SL/E VH runs 12.01@115mph with 200rwkw on the same dyno/operator.My XR6T has 304rwkw at Bruce Heinrichs Perf Tuning yet only pulls 295 back at ours,we are known to have a "grumpy" dyno.
Before my XR6T my Futura wagon,yes wagon with 20%underdrive pulley,extractors,exhaust and typhoon CAI made 151rwkw untuned(same dyno as above)enough to blow VT ss's to the weeds lol.A manual custom tuned BA with more mods making 180rwkw is not "unrealistic" at all.Dont use your mates car as a benchmark unless the same mods,car,tuner ect are used on a similar car.Even then differences rear there heads up.
Not at all having a go,just eluding to the fact things arent always as they should seem.
EDIT:Not that we will venture that way,I do see the tuning side of things really opening some hidden torque/powere from these SIDI's.Yet to drive a manual SIDI yet.
