We are both on E-85 with a boatload of other mods on top of the cam so IF you stay out of it and stick with boost that will allow you to use the original injectors and fuel pump, you should be able to stay around 21-ish. When you upgrade injectors, fuel pump (or twins like us) you burn through your take a lot quicker.

Cam, Springs, Lifters, install and Tune runs about $3000 in Temecula @ CMS. It may be more, but that's a good ballpark.

Can I say double ouch... I know for a fact CMS is by far one of the best tuners and manufactures out here in SoCal as well as they mark high. l'd love to be in the same level with all the goodies but for now I guess I'll stick to LT's, KB fuel booster and LS9 injectors. How much HP will I be with just these modes including the cam

With their stage 2 smog legal blower cam, LT's, CAI, ZL1 pump, OD cogs, 3.6" pulley (9#'s of boost) and Bosch 1000cc injectors (way too big for this setup, but I knew I was going to grow and didn't want to replace stuff multiple times) I was just a hair under 600rwhp on CMS's Mustang dyno (645 on BBK's Dynojet) and I was still getting 19+ mpg and driving like a jackass. Made it back from Las Vegas in 2 1/2 hours (stopping in Barstow for gas) and averaged just over 23 m.p.g.

That setup is amazing. If I were to do it over, I would have went with the stage 3 cam since I put the LT's on and it wouldn't pass smog anyways. I was at the limit of the ZL1 pump though.

ECS BIG BLOWER CAM!

Here is our the results of our JAMCAM-PD (228/238) with a Heartbeat blower.

Same proven lobes that all our JAMCAMS run.

Nice lope at idle with excellent driveability.

Who will be doing the install and what are they quoting you if you don't mind me asking?

Im going to have CMS do the install. And quotes don't really equate with me considering i already have all of the pieces for the install. Just need the install and tune. Im shooting for high 6's with the cam but i guess it all depends what my boost drops to with the cam (At 10lbs max boost now). I may or may not pulley down to produce more power.

Well see what the BTR stage 3 puts down with my Heartbeat in the following weeks!

If I'm correct 563 with a tvs and 631 on a ecs kit?

Nope 563 with the TVS and and 631 still with the TVS and the cam swap.

What do i need to hit those numbers? Would i need upgrade my fuel system and injectors? Stock pulleys?

I would also consider contacting Matt (LT1Z) from gptuning in California. He is one of the best for custom cams. I will be using him once I'm ready to change cams.

I'm running a BTR Stage 1 PD cam, LSA supercharger, kooks LT headers and 8psi boost. I made 637rwhp/580rwtq. I get 21mpg on the highway with no loss of drivability. My car is an LS3/M6. Everything installed and tuned at ADM Performance.

Nice numbers. That's my goal to hit those numbers. Did you have to do a top end cam kit? What fuel were you on when it was tuned?

I have the matching BTR valve spring set up to go with the cam. The heads are stock as well as the throttle body. It was tuned with 93 octane pump gas.

If your not stomping on it your mileage can be quite good. Hell I average 21 mpg at 80mph on the highway.
