Had my car dyno tuned a while back made 313/331 with just catback and lid but around 3500 it started losing fuel pressure and flattening out and I found out it had a leaking injector.
Since then I've replaced the fuel pump and put some fuel injectors that the tuner suggested would make a small difference in power as well as deleted the emissions.
So my question is how much more power should a catback and lid car make with proper fuel pressure and do you think the injectors will change much?

Car is a m6 and it dropped to almost 20psi before the pull was over

My car with lt's, lid,ls6 intake and flowmaster cat back made 355/372

330 rwhp isn't out of the question for a strong running car with a lid and catback. What year is it?

Its a 99 I was thinking it might be around 330 when it's all said and done too with the way it flattened out up top

330-350 is common power for bolt on m6 cars so you should for sure be in that power range.

This car is just a lid/catback car so I doubt it will hit 350.

Also, out of curiosity, what kind of dyno were you on? 372 torque is the highest I've ever seen from those mods.

Yeah I don't expect anywhere near 350 but I'd be really happy to see 330

I wasn't saying he was gonna hit 350 im just saying I have seveal friends with ls1's with similar mods making power between those numbers.

And it was dynoed on a Dyno jet.
