I bet its Intune? <{POST_SNAPBACK}> I had my car dynoed at my new Tuner, it measured 250RWKW, the original tune was done at intune 1 year ago and intune said I had 266RWKW, my new tuner was not impressed with the tune, boost comes on too strong and the A/F are not the best, he said it was lean. I have since fitted and intercooler and hi-flow CAT and waiting for a time to get it on the dyno as he is booked out, so till then I’m driving it easy. My best time on Gtech was 13.3 with my 250/266RWKW. I'm not sure if Intune has improved in a year but im not going back. <{POST_SNAPBACK}> Its proabably the IC and CAT you have fitted since your first tune that is making your car lean out, so maybe not the tuners fault to begin with.
