- The Eurocharge 6.3 AMG V6.0 ECU Review (Dyno Inside) -
I have AFE dry filters and am very pleased with them.,...BUT....when I had Tony Lawshee at Buckhead Import Performance do my tuning and dyno-ing he showed me 1st hand that there was zero difference in output between factory filters and aftermarket....strapped to the dyno he made a pull with aftermarket (389rwhp), changed out to factory filters, made another pull(389rwhp).....I didn't have ROW at the time but was told that they did make a difference in output(said average was around 8hp)....this was at a tuning shop that rolled M156s through all the time so they had ample experience with what worked and what didn't.
You have it backwards, you NEED to have Row boxes to get the added benefits from the AFE filters. Without the Rows the stock airboxes cannot flow enough CFM. If you add row boxes with stock filters you STILL get zero HP difference (We did 6-7 Dyno'd back to back of both setups.)
It is NOT the Row boxes that make the power, it's the filters, but only when you get the Row boxes together.
Also, you cannot do the dyno test on a bone stock car because the ECU is constantly limiting power artificially so of course it will show no difference. That's why there was no difference. Stock tune limits airflow by not letting the throttle body operate at its maximum potential so of course it won't show anything on a stock setup no matter what combo you do.
In tune grand scheme of things the only way to get the power gains on the intake side is to do everything at once (that was the whole point of doing the dyno test). And without a tune there is zero point in doing the dyno test at all as the stock tune is heavily sandbagged to begin with.




I have a dyno with row boxes and fresh oem filters and I made 400whp on stock car development package but I never dynoed it directly after tuning and afe pro drys.the end result after 15 pulls was 442whp on an aggressive 93+ file custom done or tuning.

If this was in relation to mine the opposite was actually the case.....I had the aFe.filters in for prolly 4-5000mi when I got to the shop for tuning...Jason actually grabbed a pair of OEM filters off the shelf to show me there was no difference....but again, what I saw on my own pulls doesn't make my opinion that of an expert or give me the ability to provide wide spectrum feedback.....those guys made their statement based not on what they saw on my cars pulls, but what they had seen as the MEDIAN result after dozens if not hundreds of M156 dyno runs
I wish I did another pull with pro drys but i also didnt have a bone stock dyno with normal boxes and fresh filters.
the op probably didn't make any more power because the old ones were dirty and clogged up.

Gotcha!!!!
