VWR Intake disappointing

In 2 VWR intake kits, my MAF was loose as hell. The weather seal wasn't compressed at all. I was seeing trims in the 5 - 8% region with my pipe modified to nip up the weather seal. Would probably be higher if I left it! For reference, my standard intake with a brand new MAF and running stock software is showing <1% trims. 8% is a big error if OEM is that close to zero. The ECU is bunging in nigh on 10% more fuel than it needs to, and remember that's a long term average, so can spike to higher percentages. Keep an eye out for black smoke, crap mpg and poor off boost throttle response etc.

I guess I was lucky mine was better finished. The last time I checked my LTFF with the TTE420 file they were <3%. :confused:

Wow that's great :happy2: You definitely got one of the better intakes!

My LTFT is -6.3 hopefully the revised part rains it in a bit
pudding:
A variety of differences there! If the intake is as free flowing as claimed, a small positive adjustment is to be expected, but it shouldn't be any more than 5% when the engine isn't working very hard.
Shame the LTFTs only record idle and part throttle trims. It would be interesting to see what the trims are at full throttle.
csrigo:
Been working away so not had much time to drive the car lately. I did note my LTFT values the day after fitting and it was sitting at 7% so not good at all. The throttle response low down has dipped marginally....im away for a RR today at a place I never use for a comparison to my last run a few months ago pre intake so will see if there are any gains...it defo feels stronger in the higher RPM as you wld expect...will post my graph later
