Mine was 93kpa up top on the pull with volant. 97-98kpa with open throttle body. Both 28 degrees and 12.8-13.0 AFR. IAT was 70 and 110.

Have logs from the pulls?

the pcv is deleted... the breather really stinks the car up so i'm going to a catch can.... i think for now i'm just going to delete the cats.... i'm most likely going to do a procharger so i donyt want to waste money on the intake changes... will be changed anyway later... i'll try to round up some 2" headers if i can find any that match up to my exhaust or see if B&b can make em.... i'll prob hit 515-520 just with the cat delete.... i don't think b&b's cats flow as good as a random tech cat or even the ones kooks uses....

i know 11.9-12.1 is considered pretty conservative, but with the shitty fuel we have and how some of it can have as much as 20% ethanol in it which messes up the stoich, leaving it at that is best for long term reliability imo, i'd rather loose 10 hp than risk lower engine life

id say speed density tune to get rid of the maf and ported 102 fast. i did this with my car when i first fut the 403ci in i went from unported 92 to ported 102 and got rid of my 100mm maf picked up a good amount. then get a 1 7/8 or if they have a 2" header id go that route should get another 25-30 out of it

i wanna keep the maf and tune as a 1 time deal.... dont want to have to change it with the weather of if i'm going to a dif elevation on a trip.... plus i'm not positive a 102 will give me that much of a boost... currently i'm just thinking about cat delete and maybe 2" headers if i can find them... I'd say cai aside exhaust is my biggest restriction... i just dont want to spend the money on cai changes cuz they will have to go away for a procharger anyway
