Hi all.
To give a little back story I've had my Cupra since November 2011 and regularly got 50mpg+ on the way to and from work and VERY rarely below 40mpg even when pushing it.
I then did a few mods, Stage 1 remap was included with this. No RR as they didn't have time to do it that day but they are a very well known and trusted remapper but I'll mention no names just yet. The car was fine, didn't really feel any differences but I don't boot my car often, I mostly wanted it for the increase in MPG.
I then went to a meetup at said remapping company and participated in their RR runs. Bare in mind I go 50mpg on the way there. After the first runs my car was producing 173BHP which as you all know is very low for a stage 1 remap and a fair bit down from the usual 200bhp quote which they state as well as MANY other companies. I spoke to them, they had a play with their laptop on the car and chucked it back on the rollers. It produced about 185 then but had a big dip in the power band at 2250-2750 on the revs. I was told it may just be full of crap and need a spirited run to clean the turbo etc all out. This seems plausible as, as I say, I don't boot the car often and use it to commute every weekday. So I proceed to boot it on the way home and get 35mpg roughly, I also felt a shudder on the revs between the stated revs, like the car struggled but it smoothed out instantly over 2750.
I then proceeded to drive to work and never got over 40mpg. I never have since to be honest. I contacted them and asked if they could put the standard Stage 1 map back on for me so it would be without the modifications they did at the meet up. They sent me to one of their 3rd party dealers who was a pleasant guy seemingly knowledgeable and he had the car for 2 hours whilst I wandered around the town centre as he said he needed to send the ECU download off to HQ to get a map (Which I thought odd as it's a standard map for this car generally with them all being the same ECU!) but I drove the car home and still had crap MPG.
Since then I have had the car serviced, cleaned the MAF sensor, changed the fuel filter and air filter and cannot locate what's going on. I drove to the shops with the MAF sensor disconnected to see if that had gone and the car drove like crap so the MAF must be working.
I have ordered the smaller EGR gasket but not fitted it yet as i'm doubtful this will fix the issue.
I do have RR prinouts before and after the modifications were done if you guys want to see them but I really have no idea how to fix my car and I'm falling out of love with it as it's costing me an arm and a leg to keep topped up now. I average around 32mpg from 50mpg!!
Help please!
