drop in power until 3000rpm, FINALLY FIXED BY STATLLERS!!!!

(1/17) > >>

Hello folks, I noticed ,y car felt a bit sluggish this week, so popped into PDtuning for some advice :wink:He advised some datalogging, which I did, and found that for some reason, it isnt getting near peak boost until another 700rpm in the rev range, which explains why it feels sluggish at lower rpm.
Has anyone any ideas as to what could be causing this? Surely cant just be the heat? I've swapped the DV over to a one I had in the shed, which gave the same results. also MAF values look a lot different also
Heres 2 logs, first one is from the other month, last one is from today, both running same revo settings

its not making requested load, look at the difference in the load column, its huge. I will look over the logs you emailed and report back......

Thanks Dave :happy2:

MAF might be the cause I reckon ......it's not reading as high as last month at same rev points - hence engine loading gets affected and you're not getting full boost

I've already swapped the MAF over :sad1:
