i am not sure if i am tuning this thing right...but yesterday i did multiple runs around the block (at a friends house in the middle of nowhere) and when i first started out...i went WOT and boost shot up to 24-25 lbs in first gear and the knock meter redlined instantly and i let off completely...this was pump speed MAXED and pump spray on point at only 10-11 lbs of boost...(this is a dual nozzle smc kit btw)
soooo...i decided to turn down the boost...got it to where the rod was barely tugging on the wastegate hook...tooker for a spin again and this time WOT boost was 21-22 lbs and this time i got no knock at all...i turned down the pump speed a little bit down to 8 and spray on point was still 10-11 lbs...
now...when i have this same setting with 2 other people in the car...it seems to redline the knock meter again...or sometimes it goes in the last orange...same 21-22 lbs of boost and everything...why is my car so sensitive to extra weight in the car??? with just me the car doesn't knock at all...when i add people it knocks like crazy! what should i do here? this is on a factory stock motor with just valve spring upgrade, te-44 turbo, 50's, extender chip with 22 degrees timing...
how much boost is everyone getting on a dual nozzle setup? i thought for sure i would be able to hit 25 lbs no problem...guess not...
