Ok guys, finally scrapped together some money for some more mods to my car. I am looking to do LT headers, true dual, and a pcmforless tune. Right now I am running the stock exhaust with a magna flow muffler, CAI, and a Z06 Maf.

Question is how much horsepower would I pick up from the above mods? I am hoping with the tune I can finally utilize my bigger MAF, even though I don't really need it right now......

Thanks guys.

 

I would say around 35-45 at the wheels.

 

im not quite as optimistic as Red96Lt1

i would guess closer to 35-40 at the fly,

maybe 20 hp.

but then again i didnt have headers before i blew my engine, so i cant even go by the sotp difference.

 

I was hopping to get 20 to the wheels just with the headers and exhaust, then maybe another 15 with the tune, so 35 to 40 I guess was what I was hoping for.

I figure stock exhaust going to LT and true dual has to be quit an increase.

 

20~25rwhp would be my guess.

 

I would say 20-30 rwhp
