will it hit 400 rwhp
will it hit 400 rwhp My car dynoed 380 rwhp before I added the following 4 mods. Do you think it will reach 400 rwhp after I get it retuned for the mods. The last time it had a ory pipe and cutout for exhaust. I added the 2.5 true duals, asp u/d pulley, S2 throttle body and 4.10 gears. I also just replaced my worn out vavle springs with Patriot Gold duals and gave the car a good tune up. I changed plugs and msd wires, new fuel filter and air filter. If all of that don't gain me 20 more rwhp, it's up for sale. 
Will it hit 400?

I'm happy with it now but it will be even better once it's retuned. 
well you had pretty free flow exhaust with the ORY and cutout, so changing to duals isnt going to gain you all that much... maybe 5 rwhp.. The UD is worth 5-10 like the poster above said. Problem is you added 4.10s, those alone are going to suck up any HP you gained with what you added and prob eat up a little of what you had. Depending on how far off your tune was, and if any of the PM things you changed help you may be able to hit the 400 mark. Also take into consideration on the weather when you bring it in and compare it to when you brought it in before.
