Nicks Garage, 572 HEMI, Here we go....

RAMM noone competent is questioning your work, I'd have peace knowing you did another good job. Then sit back and watch the Sxxxshow laughing. Like someone has mentioned here, you have no control over what people do with your stuff after it leaves you. You have data from the build and dyno details to back it up. Yes, it's troubling that the Ytuber guy suggests this or that may be wrong with aspects of its design or execution. Especially that he apparently knows you and your work!!! The reality anymore is most good engine shops only use word-of-mouth advertisement which is probably best at this point because most shops I know of are still turning away work from being busy (selecting good customers!!!). The Ytuber might be able to do milder/easier builds fair but, !!!it's obvious!!! some things are over his head.
