Church's dyno reads high - well established through multiple comparison threads... If you really want to compare across dynos, the most comparable would be an SAE or STD dynojet to another SAE or STD dynojet.

Any of the dynos fulfill their primary purpose as a tuning tool and are great at documenting gains (or losses) through modification. Congrats to the OP on a solid gain from the tune.

 

I agree with this statement. I just made my appointment to Stillen for dyno tuning. I mainly called Stillen because it is a closer drive for me than Church's but I also found out that they will be way cheaper than I had gone to Church's. I think I'm done with all my bolt-ons and its time to get it properly tuned. I already have the Osiris standard w/etune from a member here but have since added a few extra parts. I'm not looking for "glory" numbers just making sure my car is running the best that it possibly can.

 

Lol. It is funny looking in on all of this as I am looking on whether or not to get a tune on my 2004 G35 Sedan. Truth be told, the guys at Stillen told me that I should not expect much, if anything at all, from a dyno tune in regards to HP based on my mods (5/16 plenum spacer, Stillen Catback, R2C CAI). I know this and just looking to have my powerband efficient and get the afr back to normal.

@Terrorx7, I am getting mine done at Stillen on 4/18. Let me know how it went. I don't hear much about them although they are Uprev certified.

 

So I had my appointment confirmed then I get a call from Stillen saying the dyno took a crap or something. They would call me back to re-schedule once they get the dyno working again. I have not heard back from them since.

 

If they do tune your car, they would tune it safe where you barley feel anything. I say go to churches automotive.

 

The fact that Stillen hasn't called terrorx7 back and the lack of threads about them now has me a little worried. I hear great things about Church Automotive and the price for the Uprev tune is about the same. I am going to cancel my appointment and head over there. Thanx Bluedevils95.
