I have the Thunder Racing 224 cam and Hooker LT's. I am wondering how more HP I can get from

1. Ed Wright custom tuning
2. ported MAF ends: (Ed will program for the MAF ends so I will not run lean or get any KR)
3. Hooker catback: rather than my stock WS6 catback with a flowmaster muffler

I will have these all on soon and am wondering how much more power I will gain. Right now my O2's at WOT are pretty rich (.935-.940) with only 18-20 degrees of timing and my Ltrim show partial throttle is lean (6-8 for Ltrims)

What will I be around for rear wheel?

 

The gain from a ported ends is nothing on a properly tuned car.

Assuming the flowmaster is free-flowing, the exhaust may add a few HP, the main benefit being the bigger I-pipe.

Fixing your tuning could add 10 - 15 HP given how low your timing is. Before spending $500 on EW, I'd borrow a MAFT and see what you gain from that.

 

I borrowed a MAFT and got my ltrims near 0, and my WOT 02's around .900 with no KR, but my timing was still low between 18-20. I was hoping that the tuning from ED Wright would help my timing and throttle response. Also, with the MAFT dialed in right, I still can't get it to idle well with my cam. After he tunes my pcm, will it idle like it did stock?

 

EW can fix those and you can sell the MAFT when he's done.

You may need to bump your idle speed in addition to adjusting the fuel mixture to get a stock like idle.

Get some ATAP logs for him: O2s, timing, KR, LTRIMs at various speeds and loads. Also decide what else you want to take care of such as deleting codes, T-Stat temps, rev limiter, etc.

BTW, Superchips is in Florida. Maybe you could dyno tune your car there.

Is Superchips as reputable as Ed Wright as far as tuning? I would rather drive my car there then ship out my pcm.
