churches dyna pack vs raceline dyno jet. My results
Church automotive testing here in so cal(Wilmington, ca) tuned my s2000. The car runs great but I just wanted to see what the car would do on a dyno jet. Churches dyno pack is always known to read higher than normal. My s2000 was tuned by Shawn church and made 385whp on his dyna pack. I ran the car today at Raceline in Temple City,CA with their dynojet and the car only dynode at 326whp. That's a whooping 60hp less!.
My car has been boosted for over 15,000miles. I have 0 problems with the car or the tune. My wide band shows about 14-15 on idel and low 11"s when in boost. But at the dynojet at race line, their wideband is showing 13.5 almost 14 to 1 air fuel in boost. Is this even possible? If that was true should the engine just blow up?

Yes I understand that but 60whp from a mid 300whp car seems kind of a lot. But more importantly raceline's dyno jet is showing 13.5 to 1 under fullboost. They make it sound like my car was tuned like crap and will/can blow up at any second. My aem wideband shows low 11's under full boost and they said my wide band is not right. I know church tuned my car for low 11's for the air fuel. Like I said the car has been driver for over 15,000 miles turboed and even autocrossed with 0 drivability problems. So either my car is running lean and is going to melt a piston or race lines wideband is way off. If the car was really running 13.5 to 1 air fuel shouldn't the motor already have blow up?

Trust your wideband, not a tail sniffer. A good working tail sniffer reads .5 leaner then actual. Many times its hard to get an accurate tail reading at all. These guys are trying to sell you on a retune, tell them to take advantage of someone else and fock off.

Dynojets are the most accurate account of the power you are truly making on the street. They can not be manipulated like the other dynos and are very accurate. Take it to the track and your mph will back this up.
