Boost always does feel amazing for one of the first times you drive the car....

about that equation, idk how it works, but on my 84 300zx i had a z32 maf and was dyno tuned at 462whp at 22psi and my maf was at 76%...

76 x 550 = 418hp....so a bit off

on my Ka-t which is a t25 setup at 8psi i hit 89% yesterday so idk if my car is weird and is making more power than its supposed to or what...cuz at 8psi i should only be like 200whp max....and arent the stock maf's good to 250whp or so??

im not going to blow my motor. trust me, i just spent over $4k and did every single bit of work with my bare hands. i wont let it happen. ive got fuel and timing control. i pigged the fuel a little bit from some numbers i got from someone off of here that has almost the exact setup i do and he got his numbers by street tuning with a wideband. ive got my timing retarded 1 degree per psi. its running rich because i can hear a little bit of gurgling going on and a few pops when letting off the gas. it doesnt really pull that hard when i get into boost. the transition isnt really smooth at all. i know its because i richened it up. i want to lean it out and hit it, but im not going to do that because i want to get it tuned at 15 psi on a dyno. i was just wanting to see what itd do when i hit it full throttle and see how my work payed off. i drive normal everywhere i go excpet for when i made this post and when i installed my itc. plus i dont even have my bov on yet. i just need to get a flange welded on. im being conservative till i get her strapped down at titan.

386-747-9982. Give me a call when you know your going to sr 50. I"ll make the hour drive to come meet yall. I'll be on the coast so I'll just take 95 down to sr 50 and then cut across... The meet for daytona starts at 5 and will probabyl last till midnight or l8r. Don't feel like go-kartign that much but might have to do at least one run Do you have a wideband port on your downpipe??? I can bring my NGK wideband and give you a tune
