hi guys.

I have owned mainly Nissans as this my first Toyota. I have mapped all my cars since i had mapping done by a well known tuners which was not what i expected. Done plenty of nissans(s14,s13, r32, pulsars) for friends and locals and am known locally. As this im my first toyota its bit of a learning curve but am getting there, slowly but surely. Always used E manage as all friends cars are mainly road cars and is pretty cheap.

Homer mate, I did use the xs power manifold and wastegate and yes i do have an overboosting problem. I will be taking the manilfold of soon and try grinding the welds and maybe modify the dump pipe. I have already pulled the wastegate of to grease up the shaft etc. You get what u pay for , can't turn back time would not have bought it. Dyno figures were at hubs @ 1.35 bar.

 

my overboosting problem was because the pipe to the wastegate was tiny, had it opened bigger and problem solved;)
