So I'm thinking about swapping my TVS 2.3 for a Whipple 2.9.

I have a guy that's willing to buy my TVS for about what it will cost me for a FRPP badged 2.9 Whipple. With the 2.9 I should pick up about 25 - 35 more RWHP on a 91 octane tune putting me right at 700RWHP STD or 680RWHP SAE. The Whipple will run more efficient, produces less heat and allows me to take the HPs up into the mid to high 700 range and maybe 800's with additional mods. The only catch is initially I might have to buy 72lb injectors ($620) and I might loose a little bottom end "grunt" the TVS makes.

I know more is better but I'm at the point were I can't use the HP I have because of traction issues.

"Yes" swap them out or "No" keep the TVS?

On a side note I know a guy who has the same setup as me but with long tube headers and he's at 711RWHP on a race fuel ...... maybe I should just add headers and move on.
