Hello fellow butt hurters, i found a Mr Gasket performance chip new in the box laying around, my friend has a 90 formula with an 85 camaro 305 tpi.. would it be a gain for him at all? He has just a very mild cam and shorty headers and exhaust withous cats

The chip says its for a 305 HO manual, his car is auto and by HO do the mean its for a lg4 or somthing? Cant find much info but its free so if will make it run happyer then may as well do it

Any info would be appreciated!!
Thanks, Adam
