Piggy backs limits ?

[Zrain25]

I'm rebuilding my engine and shooting for 400-500hp .

Arp everything in bottom end and studs
Mhg - decked block and head
New oil pump
Standard rebuild
Probe pistons
3 angle valve job
Valve springs
550 injectors lexus afm
Fpr
Wideband
Fuel pump
60 trim ct26 or switch to t4 set up if I want more then 400hp

And tuning can I use a piggy back like a maft pro or similar piggy back or do I gutta go standalone ?

Thanks guys

A piggyback will get you most of what you want, but my research seems to indicate that there are other limits with your setup which would require more precise tuning to get there.

With a MAF-T Pro, you no longer use the Lexus AFM. (Well, or you can, but it doesn't matter if it's the Lexus AFM anymore. The stock one would be the same.) You can also go to a larger injector than the 550s, which would make your stated power goals easier.

The 60 trim CT26 rebuild is not the same as an actual T4. With an unclipped exhaust wheel, it might be limiting your flow before you get there, but with a clipped wheel, spool will suffer.

I'm aiming for similar power goals, with a similar mod list (though I have a bigger turbo) and I think that I can get what I want with a piggyback. (I've got an Apexi Neo to install.) It should be doable, but it is getting close to the point where a full stand-alone should be considered.
