Question: hi alan i recently asked how much psi my 97plate sti should be runnin and u replied 14 psi 1 bar its currently at half a bar of boost how would i go about turnin it up? cheers
Answer: Hi Darren - It may be there is something else wrong with the car which is causing that. The management will not allow full boost if there are certain faults logged in the ECU for a start. It's a complex area, and I wouldn't advise attempting to just turn it up in any way without expert help from someone who spends all day on these cars.

Question: Hi, I had my 96 impreza wagon rolling roaded by you a while back and am interested in going for the Simtec ECU in the neer future. It currently has a TD05 but a standard intercooler. Which intercooler would you recommend for around 300 and how long do you allow for fitment and set-up of the Simtec? Many thanks, Simon.
Answer: Hi Simon - Sorry for late reply, I've been on holiday for a week. You have a couple of options, either a larger top mount, or front mount if you intend going for it! 300 will just about buy the kit, but be aware the fitting job takes a full day and cutting tools. We charge 400 plus vat to fit a front mount, and the job rewards care. We like a full day for the Simtek, and an overnight stay is even better.

Question: hi,you have been recomended by a mate of mine!at the moment its just got peformance exhaust and hks air filter!was thinking about a chip and remap?how much extra bhp would i gain and what would the rough cost be?thanks!
Answer: Hi Dan - We wouldn't use a chip as such. If yours is a 1999 version 5, we can re map it using Ecutek software. We charge 500 inc vat, and get consistent good results! We'd expect to see at least 30 bhp over stanadard, with around 40 ft lbs extra torque across the range. If yours is the earlier version, we would use a Simtek plug and play ECU. cost at the moment is 995 including vat for supply, fit and map. Call Martyn on 01752 345880 for more details!

Question: Hi Alan, i have had an impreza sti version 8 (type uk) for 2 months now. It had the prodrive performance package so should be 300bhp. How much power gain would uprating the ecu give? And then how much to get it in to you and get it done. Cheers
Answer: Hi Tom - In practice, it's unusual to find a Prodrive converted car giving 300 bhp. The tendency is to find the boost raised in the lower rev range, which quickly drops back as the revs increase. The net effect is very safe, but conservative power, a torque increase, but nowhere near what can be achieved. We would expect 330 bhp or so from an Ecutek remap, assuming a decat or sports cat downpipe is fitted. We charge 500 including vat for the remap, and we can quote for other work should you require it. Please call myself or Martyn on 01752 345880 if you would like to discuss ?

Question: Impreza- hi alan no the speedo cable isnt in the back propely but its been like that for some time now if this is the problem how do i reset the light cheers
Answer: You need to sort that out right now! If the check light is on, the car will be in go slow mode for a start. First fix your speedo. Near to where the black wires are under the dash, you'll find a pair of bright green multi plugs, each with two flat terminals, that will plug into each other. They may be taped to the loom with blue tape. Now listen carefully, as I'll say this only once! You plug the black wires together, then the green wires. start the car up, and drive for a short period, say 200 yds. By that time, the ECU will have re-set, and the check light should be flashing continuously, indicating no faults. Stop the car, turn the ignition off, and unplug both sets of wires. Assuming you've fixed your speedo, that should do it! If you have high octane fuel in you tank, that would also be a good thing, as the ECU will re-set to the more advanced level.
