				TimeTrial car, need additional 5-10hp
			 
			 
			
		
		
		
			I need to find 5-10ho in my NASA TT5 car, it’s a 2.5L w/ headers, no cats, full exhaust, and a underdrive pulley.  Is tuning an option?  Poking around on the Internet it doesn’t look like this is a popular route. I’d rather not buy a 2.7l engine but might have to.  Any ideas?  If tuning is an option what do you all recommend? 
 
Cheers, 
Stu
