my car made 324 on 4B's dyno and then 347 on springys

I have the exact same thing on my FG!

Ok thanks will do, will let ya know how I go

I live on my own island in the pacific ocean, it consists of just a racetrack and some workshops and a small house, I make the laws so no cat is required. Dont think it would be a muffler as it was hitting a laggy 17psi right until I gutted the cat now the responce is much better but it stops at 15psi ?.

Hi guys, had my FG tuned recently to 17psi but shortly after it became really quiet and laggay as the hi-flo cat had started to collapse, We decided to hollow it out to see what difference it made, the responsivness of the car increased and it hits boost much better but it no longer hits 17psi ??? max boost is only 15psi. I thought removing the restriction would possibly cause overboost not a loss in boost? if anyone could explain it would be much appreciated Thanks, Mods are as follows; Hdi Cooler 4" battery side intake GT3540 with ar.70 comp cover ported wategate 12psi actuator 4" Dump 4"in 3"out Cat (5" body) standard 3" Catback with rear muffler removed siemens 60lb Walbro pump SCT Engine and ZF tuned

I was listed as the driver and was also charged by police for driving a high powered car on the day... I honestly thought I was screwed.

Stacked my fg t on p's in victoria, insurance company payed out no questions asked.

My FG on standard 18's and king springs, cant remember exactly what springs they were though :S
