thats got to be a good street / spirited rate.
IE3 were my fav for a lot time and they are 350/500 IIRC
The aluminum monster got 500/700 and it was still good for the street but on the stiffer side

Engine break in
Injectors
Front bumper
Stainless steel zip ties instead of regular zip ties for the exhaust (they're not directly touching the pipes at least)
Smog
Take it to a body shop
Take it to an exhaust shop
Take it to the dyno!!

Yea, I suspect the M3 pump may well have been on its last legs, when I flow tested it, it was only flowing 105lph at 3.8b, considerably more than a stock M20 one was though. The M20 pump was a brand new Bosch unit, went back to Bosch for testing and they reported there was no issue with it.
My car was live mapped, took 4 attempts due to the fuelling issues I was having.

I can only talk from what I’ve experienced with my car, and I needed to do the mods I did to solve pinking and power loss at higher revs, I also need to run on 97 RON fuel. M50 injectors alone we’re a long way off being up to the job.

i'm running 1.5 x the fuel flow of stock engine with stock regular and pump. back when i didn't have a way to tune the ECU i did bump the fuel pressure upto 52-55psi with 21lb injectors at the time and ended up with 3b and 24lb about 80% duty cycle at max hp on stock fuel system with bigger injectors.
sounds like other pumps were shagged
97ron is to be expected (probably 93 PON) as you have the higher compression slugs right? so about 1 point higher

You dont need more fuel pressure you tune the pulse width at rpm and loads it requires more or less fuel. Adding fuel pressure increase fuel flow at all times. Stick to a mild Increase in injector for that
E36 M3 pumps run at 3b, E36 M3 EVO pumps run at 5b.

Nothing super major, I already knew the car needed some work, I got it for $180 after all, but it's a little disheartening seeing the gaps to the fenders. This was the first time I put on the hood fully.
