Question: 2000 Impreza -Check Engine warning light ? Once a day / week the light comes on, The car will drive fine off boost, But trying to drive the car on boost it seems to \"misfire\" and splutter, But stopping the engine and re-starting cures the problem till next time, I have always kept the maf and throttle body sencors clean, but this is not helping, I have looked at several different impreza forums about this problem, All of which suggest it could be several different things at fault, Any ideas ? Thanks.
Answer: Take it to a tuner, it's what they are for! The first thing is to find out why the light is on by checking fault codes. Sometimes you can get false readings caused by HT shorts from plugs or coil packs. Checking both the on board diagnostics and the plugs/coil pack should find the fault.

Question: Hi, I have a 20VT powered MK1 Golf, which I\'m in the process of fitting a NOS kit to. Firstly do you do nitrous refills? And how much? Also I\'m after getting the NOS setup optimised on the rolling road. How much am I looking at for this?
Answer: Hi Paul - Regret we don't do nitrous refills. I believe there is a guy at Yeo and Smith in Plymouth who does, or certainly used to! their number is 01752 262776. I'd allow 120 plus vat for the dyno time.

Question: Hi How much to remap a 99uk turbo. What other options are available mapping wise Cheers craig
Answer: Hi Craig - On a 99 car, using Ecutek software is the only option. A remap costs 500 inc vta, which includes the licence from Ecutek. I'm assuming it hasn't been mapped before. We would normally expect as much as 45 bhp gain from the first stage map, depending on actual spec. There are too many options to list on here! Please call me on 01752 345880 and I'll go through your choices with you.

Question: Hi alan, How much would it be for a decat and remap on a sti 04, also what would the BHP, Noise and MPG. be like? Thanks, Mike
Answer: Hi Mike - A decat will cost 172 delivered inc vat, we could also suggest a sport cat at 277 inc vat. We can make use of either! The noise levels would go up slightly, but not obtrusive. Fitting would cost 60 inc vat for either option. The remap would come in at 350 inc vat. We'd expect anything up to 50 bhp gain over standard, with no problems at all.

Question: Hi Alan, I have an \'07 Audi A3 2.0 TDI (170) Quattro, which has already undergone an ECU remap by your good self which I have been very pleased with. I now have a Diesel Particulate Filter problem (nothing to do with the remap) in that the dash warning lamp comes up on a regular basis and the engine goes into \'limp home\' mode. I have read numerous forums on the subject and it appears it is a very common problem with all diesel engines \'07 onwards. Plympton Audi have seen the car twice now and twice replaced the DPF sensor, reset the ECU and then put it on a rolling road for a while to \'burn off\' the filter... its going back in again with the same problem on Monday! A few of the forums talk about getting the DPF removed and then re-programming the ECU so that it prevents any further attempts to \"regenerate\" the filter. The same forum talks about disabling the EGR (exhaust gas recirculation valve) as part of the process? First, can you do it? Second, will you do it and lastly... how much?
Answer: Hi Darren. Yes, we can sort that one out for you. If you can arrange to let us have the car for a couple of days, we'll remove the damn thing completely and remap it to suit. Cost around 650 which will be money well spent!
