[1969 Stang]

So we are building my friends bullet up....so far its getting to be faster and faster...he has the vortech supercharger....we want to get an intercooler soon.....we have done exhaust and are running no cats...and we are going for some headers soon...now here is my question....on my uncles 1991 supercoupe we put on a L-MAF and when we got the computer reprogramed it made a HUGE DIFFERENCE...well we want to do it to his now get the L-MAF and do it to his car......are we going to get about the same results if not more...and where can i find a farly priced intercooler for his...its the 8-9 psi version i believe.....and also the best price i can find is about 1400 or 1300 i believe. And WE WANT CAMS.......WE REALLY WANT CAMS........so go ahead and start naming good cames.....he wants it to be off the line and pretty high......Thanks....and he has 4.11's also...just thought id bring it up......thanks
