all part i have are for a larger setup. 4.8 was a testing motor/learning experience. i have already maxed out the 60s plenty of times. ive seen 125% duty cycle with 60s on this motor. 42s wouldnt be enough. at 8 psi on this setup ive seen 76%duty cycle. 42s would only be higher and wouldnt allow more boost. 8 psi isnt what i plan to run but what i got it to run and hold at. i orignally was running the combination of springs that tial gave me to see 15psi. but somehow the rating of springs for the 60mm gate are setup for 30psi. thus why the truck is having an issue now. the 4.8 spiked to 25psi at 50% throttle and 19psi at 100%

8 psi on this setup isnt the same as 8psi on a moggie. yes regulator is boost reference. again its the 2K hp model. i dont remember part number off top of head.

well i believe i found alot of my issues. first thing i noticed. i pulled my old injectors and yes a few were dripping. these i bought off ebay claimed 60lbers... they ohm'd out to be 12 for a reading. so i borrowed a set of 42s for now. they ohm out to be 16 these are bascially brand new. i installed these and didnt see any drips. but pressure did drop again. when i took rail off i noticed i still have fuel in the rail that the regulator was mounted to. well i went over entire feed and then took it part. i pulled filter apart and notice debris in the screen. i also notice some real small particles that might of went thru the screen. [might have clogged injectors]. well i cleaned filter and noticed the liquid i was pouring thru was coming out other side of my line. so i tore it part at the checkvalve. and noticed the flap didnt seem right. cleaned that and tested. yupp it leaks. tore it apart and tried again. again it leaks. it holds air one way but doesnt hold liquid. so my bleeding off is from the walboros and the earls check valve not working so i wasted money with this product. [over winter going ot make some changes now]

next issue to address. see if the spike hurt motor....

did a compression check and motor reads as follows
1=150 2=145
3=145 4=145
5=150 6=145
7=150 8=145
these were all done with a snap-on gauge

ok next test was a leak down. so i started pulling valve cover off to check for valves being bent again and good. as i noticed i pulled the booster line and i had vaccum on this [good sign]
so did a leak down and this motor is claimed to be a 7k mile motor

1=2% 2=1%
3=1% 4=1%
5=1% 6=2%
7=1% 8=1%

guess motor checks out. so tomorrow going to toss plugs back in and give it a try again. i believe my fuel issue was the bad injectors....least motor is sound

Sounds like your diagnostics finally found the culprit!
