I had a new engine put in as mine blew a couple years ago - it's down 37hp and I'm not feeling the same throttle response. With the new engine all rods were upgraded to billet - I sent out for an email tune - just curious to see the difference.

I am guessing you should be in the 600 ball park.

I should have said 650ish. Just my guess

A lot more than stock.

Yes it is a lot more than stock !

If that FRPP TVS is the first gen (black case) then its very restricted inlet wise compared to a Trinity or VMP Gen 2. You may want to consider a case swap to a VMP Gen 2 if they still have those cases available.

600 RWP is a good estimate. A higher flow case should be an easy 60-70 RWP.

tvs is still a tvs --- and you got headers. I guess a lil over 650. port that tvs or get a better case and around 700.

600 or so I'm bettn on a Mustang Dyno if on pump gas with no methanol as fuel. on E85 720 or so.

FRPP TVS is more restrictive than the Gen I TVS VMP introduced in 2011. Without opening up the inlet and getting a larger elbow, I don't think you're going to see much over 600. I believe the Gen I is basically the same case as the FRPP with the inlet opened up and a port matched elbow that was matched to the revised inlet. You should be able to replicate it and get another 60 - 75 hp, give or take. While all TVS rotors are all the same, the cases and corresponding air flow have improved with each iteration.

Dynojet 630-640rw ?
Mustang Dyno 580-595rw ?

All depends on the tune ,my stock Eaton with full bolt ons made 630s rwhp on 93 and 680s on e85, with less than 15 #s of boost, and that's threw a 4r70w

But dyno #s mean absolutely nothing time slips tells the truth all dyno's show different

Are you running headers too?

Why rely on an e-mail tune? Trailer or drive it down to Blankenship and have him tune it. It will feel like a different car with a quality dyno tune.

Yes very cheap obx long tubes and x pipe
