Acceleration hesitation

[jett]

its a 4g63

it was safe tuned

its really good on fuel

You got i dyno tuned.... It's not that i don't trust your tune/tuner its more that i don't understand how that table/ecu works...

Usually you need more fuel higer in the rpm & higher in the MAF - yours is the opposite. I'll have to look at the map and read up on the ecu..

Here is a what mine looks like - so you see what i'm getting at

Also if you have an aftermarket ecu - don't bother tuning it with 98RON - my car is tuned for 91RON and it runs beautifully. For 3kw loss i'm not paying through the nose for petrol.
