Hello I have an Acura RDX 2010 sh-awd and I was wondering what mods I should do next to gain more horsepower so far I have done

K&N Intake
RV6 Downpipe
ATLP catback exhaust
Hondata flashpro and I got it tuned
I also have on the way 300C DW fuel pump and 750 CC DW fuel injectors and a Rywire harness and plan to run e85

what should I do now to gain more horsepower?

 

Larger throttle body/MAF. You're about to give it more fuel, so it will also want more air.

Who did your tune btw?

 

which throttle body should I go with ? I’ve been trying to find out but I can’t for the RDX and I got it tuned by Real Auto Dynamics but I plan to retune it once I run e85 to make more horsepower.

 

It seems the ZDX throttle body is the way to go https://acurazine.com/forums/1g-rdx-.../#post15046945

 

750s won’t be enough to max out E85. You can tune for it, but you’re going to run out of fuel before turbo even on the stock turbo, so you’re not going to get the most out of it. 1000s and a Blouch turbo upgrade are a better alternative.

J35/68mm throttle body is the max for the stock intercooler hose. If you go larger, you’ll need to change that out and then you may want to try to find a tapered one. The stock intercooler outlet is small.

Don’t touch the MAF. Speed density tuning is your friend.
