FS[SoCal]: Osiris Tune (Church Automotive) SoCal
#18
the only difference between the WHP numbers on the dyno and real life WHP is when your have you actual rims on the car, the weight does make a little a difference.
when your getting the tune they took the dyno up to your wheel hubs
I know user: butkiss1 is way faster with his 17's on vs the 19's

I have to let the guys at Church know who I sold the certificate too, so let me know if this is for you or someone else.

I don't think that's accurate. I think it's $200 to buy a coupon for a $250 flash, so it's actually a $450 tune, a savings of $100 on the regular $550 price.
