last week ago i did a dyno for 40 bucks pretty good deal but the only catch was no A/F. so i was expecting to get 290 to 300 at least and when i got my results it was very disappointing as u can see im pushing 275 to the rears at 5200 rpm when it should be at 5800 to 6000 rpm. the guy told me that i have a bad tune for the kind of mods i hav on the car.



i was wondering is it possible i could blow up my motor with this bad tune? ive been running on this tune for 2 months since my motor swap.

also im throwing trouble codes.

P0600
P2105

thanks

 

The only mod you have that will make any real power is the CAI, shortys do nothing and CMRC deletes only give you maybe 3-4 HP across the RPM band. You should be better then 275 though but, without an AF ratio it's impossible to tell if the tune is bad.

 

Exactly. Its hard to tell if you're not looking at the A/F ratio.

Although, whats weird is your car starts to loose power after 5k rpms. With a stock intake, O/R H, and a bama tune I made 281/307, with a A/F of 14.7 so pretty lean. My power stays flat from 5100-6k.

There is definitely something wrong here

 

Your tune needs a little work. Something isn't right about the power loss. And the codes are showing faulty OBD II port and electronic throttle actuator fault. Atleast that's what google told me haha. Kinda weird

 

When I google P2105, I'm seeing Forced engine shutdown. I think that's part of your problem.

Who's tune is it?

 

thanks for response yea i talked with the guy who tuned my car. he worked for muscle motors and hes taking a look at it right now. hopefully i can get it in very soon

 

Get it to a tuner that has the right tools for a dyno tune. This info is useless w/o AF ratio.

 

I'm think it's the tune. Reading online, someone mentioned the code is from exceeding the torque table limit. It is not your typical code either.

 

If nothing else, swing for a BAMA tune from AM and she if she straightens out for starters. I'd be leary to let your current tuner do anything else. I'd expect to see 285-290+ with a decent tune and CAI.

+1 on the shorties being little to no help.

 

Find a different tuner before you need a 3rd engine.
