well heres the deal, last time i got to the dyno i put 220whp whit, safc, rb turbo back, walbro 255 fp, running at 11 psi( wideband set at 11.2). now i want to go again to the dyno cause i port the wastegate, put a boost controller and did the t.i.d mod( first time is was without a boost controller), but i first want to know if im gonna see a difference in whp or will it be not much of a gain. also should i lower the wideband or is it ok set at 11.2????

thanks

 

I dont think ported wastegate is a performance mod, it really is just so you dont boost creep.
I have heard TID upgrades to cone filter or none at all does little for a forced induction, maybe 2 or 3 hp???

The only thing that will make a difference is if you increase ur boost with your controller. Running at 15 PSI you might see a good amount of HP increase. Careful running at those levels with your setup atm. Seems you dont have a upgraded injector your you probally running lean.

 

yes i don not have upgraded injectors, im planning to get 720cc very soon, and one more thing, don't you think 15 psi is too much for stock turbo??????

 

oh and another thing bro, last time i did 220whp cause my psi drop from 11 to 5 whe i reached 6300 rpm, if now the ported wastegate can prevent boost from creeping, at 11 psi i should do better than last time.

 

yes...in order for those 720cc to go in effect i would get an rtek 1.7 or some sort of piggyback

 

15 is max for stock turbo. And that drop in psi is not actually due to boost creep. It can be a multitude of things from a big vac leak to loose turbo bolts to bad actuator.
