ok i put a new 995 big bore motor from k&t head is ported it has turbo cams
all the good stuff through out im running mcx low boost system at idle there is no vacuum and has no boost i checked gauge and it works fine i used vacuum pump and compressed air to check gauge at manifold so no leaks from line to gauge it idles fine have no leaks on exhaust or t-bodys im running utv billit intake to t-bodys so i adjusted waste gate rod still no boost i shortened rod as far as it will go and can only get 2psi of boost so i need a stiffer spring but my wast gate is not serviceable what im confused about why dont i have vacuum or boost now with new motor is it because of cams or more cc's am i missing something.
im getting ready to install new 1000cc inj and pcv with pti and i need to order adj wast gate does anyone have any suggestions would also like to run manual
boost controller thanks mike:ride:
