Seems like the dyno's are consistent.

This dyno is on the correct SAE correction factor, so thats usually going to show less than a STD correction.

No cats right?

Check for stored codes and clear them. Code scanner can be bought here at Walmart of all places.

I see your in the Middle East, what gas are you running there?

If sport mode is on, manual shift mode is activated and traction control is fully disabled and the dyno pull is done in 6th gear, then I would wait another 1k miles and try it again. You have nothing to lose.

Sport mode on, trc off, 6th gear pull, 95RON, catless. Even if SAE shows low #s, I just gained 4whp from the baseline which is not right. Ill look into the scanner. Can someone show it to me?

I agree with you, thats not a lot, but while many members will disagree with me on the ECM needing to re-learn, I only originally gained 5hp peak from stock to the JoeZ exhaust. Then another 7peak post header install 2500miles later. I drove another 1500 miles with the intake, headers and exhaust on and then laid down 392whp.
What im saying is that computer needs to relearn. Take some time, enjoy the car and revist the dyno in another 1k, or chase your tail.

Every month someone comes here and complains they didnt post the same hp as most others do.

I bought this scanner:

There is a port under your steering column that is plugs into. This model is a little pricy, but does a lot of things. I got mine, brand new, from a seller on eBay for a great price.

Check online, or someone here might know, but there are several newer ones that just interface with your iphone or smartphone, you just buy the plug in piece

When you hook it up it will read out codes that have been thrown. Look up the codes online and post em up here.
When its done scanning it will ask if you wanna clear them. If its a problem that needs to be fixed then the code will come back.
Most auto stores here in the states will read your computer for free...just an idea.

Other than Code reading, what should I look for? I mentioned that I had a leak from the dipstick but it supposedly has been fixed. Should I visit another shop and have them look at the o2 sensors? and what should I look for exactly with those?

I would invest in a wide band, or some other way to monitor the A/F ratio in real time. By doing this, you should be able to get a gist of what your car is doing.

The guy who dynoed the car had a wideband during the runs and mentioned that as the rpms go higher, the car keeps on getting rich.. starts in the 12s and ends in the 11s

I did disconnect the battery a couple times for no change, but most here dont have to do anything, it just posts great results post part install as it should. Others say it needs several drive cycles to learn..whatever. Im over it. I hit 392whp in 100 deg weather, im happy.

That sounds normal. Last thing I could recommend is to buy a scanner that can read information in real time. By keeping an eye on the real time information, you should be able to see if the car is pulling timing during pulls.

No that's actually getting richer.
