General How to Richen Up Without a Tune

[kcd]

Hey guys.

So I picked up a 1G about a month ago. This thing is pretty well built and is tuned with a ProEFI ecu. It got its most recent tune about a month before I bought it. When I got the car, I did a boost leak test and discovered a few major leaks (throttle body, injector seat, intake manifold). I have since fixed the leaks, so now the car obviously needs a fresh tune. But the closest tuner is a state away and I really don't have the time or money to get it professionally tuned right now. So my question is: Is there any way to richen up the car without tuning it? It's running a little on the lean side, and I assume it's because I fixed those leaks. But I'm not too familiar with the tuning aspect of things, so someone please correct me if I'm wrong. I just want to temporarily richen it up until I can find the time to actually get it tuned.

I'm sorry if this is a stupid question.

Thanks.

could bump your fuel pressure up if you have an adjustable regulator

What A/F are you seeing at Idle, Cruise, WOT, and Mild acceleration.

Turn down the boost.

What A/F are you seeing at Idle, Cruise, WOT, and Mild acceleration.

Idle- Cold- 17.0 Warm- 15.0
Cruise- 15.5
WOT- 12.5
Acceleration- 13.0-15.0

Yea you're barely leaned out. Bump up fuel pressure a couple pounds as suggested and drop boost a couple pounds as suggested and report back as to what they are.

WOT- 12.5

Yea you're barely leaned out.

12.5 is barely leaned out? OP, you better stay off WOT before you destroy something.

Can anyone tell me how to adjust my AFPR? It's a Fuel Lab. Or can you link me to a write up on it? I'm sorry I didn't do much searching. Kinda busy at the moment doing other things to the car. Always something haha.

I thought 11.5 was on the edge under boost on pump gas?

Where is your O2 sensor reading coming from? If it is in the stock rear location maybe an exhaust leak? I have small pre O2 exhaust leaks now and my idle is high 17's, cruise low 15's, my WOT is still 10 though(stock tune).

Oh durr. Should've read that closer. My apologies.

OP, you want to be running 11.0 AFR or a touch richer if you want. Other than that, either turn your boost down or just stay off that throttle.

Thanks for all the input guys! It looks like turning up the FP a bit will help me stay alive until I get get it tuned. Now I'm seeing 11's at WOT, 14-15 at idle, and low 15's while cruising.

That sounds good for now glad you could get that worked out.
