Had my car on the rollers today as i had a scoobypro ecu chip fitted of EBAY yes i know crazy right WRONG The fuelling was bang on torque was up 20 lb/ft however due to my enormous bulbous cat right slap bang in the middle of my downpipe (standard factory) It chocked the boost target of 1.1 bar and as the run was in 3rd gear i only achieved around 0.9 bar. SO as a result bhp up by 2 bhp lol and torque 20 lb/ft. The guys at triton said that if i remove the blanking plate from the bumper wing and fit ducting to the air box i'll lean it out more and get more bhp and obviously the decat

Below is my graphs b4 chip and after (Impressed with the power and torque curves compared to b4 too more power lower down)

 

Fuelling is a bit ragged IMHO.
Running around 11.5 at full boost 4000rpm which isn't bad. Then went a little lean, then suddenly richened up to being quite rich then leaning out again at the top end.
I wouldn't want in running any leaner then that at the top, as it is likley to be running leaner in 4th & 5th.

What was the AFR reading on the standard ECU ?

Did they run it up a couple of times when you swapped as the ECU may still of been doing a little bit of learning, especially on the boost. As it can take a couple of WOT to settle the boost sometimes.

 

Yeah they gave it 5 runs on the dyno and only used 3rd gear i did say to them if they could use 4th as i seem to get more boost in 4th and 5th.

See below b4 chip AFR

hmm surely you should see a better increase than 2 bhp?? torque seems better which cant be bad but id would of expected a little more than 2bhp!!

surely the down pipe cant be holding back 20 odd bhp??? i take it the more breathing mods you make the better the chip will work but hey what would i know??
