Hi all,
Me again,more questions! I have a 1999 20v Turbo. Totally standard. I am looking for a little more power and I think the gtec1 seems the best bet at an extra 30bhp. Do I really need all the other bits to go with it straight away? ie,prv? boost gauge? Or can i just stick the chip in and off i go? Plaese help because I really am a novice at this tuning stuff!!!

Well in theory, yes you can just fit it. The gtech is a well respcted chip and is plug and play, however each car will respond slightly different to it.

If you don't have a boost gauge, you will not be able to see how much you are over boosting by and if you don't have a PRV you will not be able to stop the overboosting that you can't see you because you don't have a boost gauge.

So it makes sense to fit atleast a gauge, see how the boost is and go from there <img src="/forum/images/graemlins/smile.gif" alt="" />

The standard boost control device allows 0.2 bar of overboost, so will spike to 1.4 bar with the GTEC 1 - not ideal on the standard intercooler. To remedy this, you fit the PRV to remove overboost, and need a boost gauge in able to adjust the PRV properly. A gauge and PRV is not expensive, and the boost gauge is vital anyway.

as above really, you can fit the chip and off you go if you are running the standard EBV. It will hold 1.2 bar boost and overboost to say 1.4 bar as above.

this overboost will put a lot of strain on your clutch though, and a half worn clutch thats been running on standard boost will meet its death fairly quickly if you run like this (pretty much what happened to me).

You are also at the limit with regards to charge temps at 1.2 bar with standard intercooling. I wouldn't advise gunning it from low to very silly speeds, with long hard maintained acceleration. Even just taking it the whole way through 3rd and 4th flat out will see very high cyl temps. Just have some restraint and plan to upgrade the other parts if and when you can.

The next step after the chip is PRV and boost guage, check the group buy on the nomad pillar mounts. This won't cost the earth, especially when considering how much the Gtech costs (compared to other chips on other cars!). I run my car at 1.1 bar with a prv and gtech 1, no other engine mods - have a nomad pillar pod with autometer boost gauge. Been running this for over 30,000 miles now with no probs as of yet, including 2 sprints and over 20 santa pod runs.

I think it best I leave it for now,this "overboost" and "bar" stuff sounds just to confusing!! Unless someone wants to drive to pembrokeshire and do it for me lol??

I run a year on Gtec 1 on standard car with no other mods added. It runs fine. Like the others say, if you dont spike it all the time through all the gears you will be fine!said that; there is no garanties that things could get wrong!

Hi All
Fitted mine (GTEC1) about 2-3 weeks ago and mine also seems fine.
Acceleration is very smooth and temperatures seem fine — also, as suggested by Roger at Powerfiat, it cured the continual stalling problem that I was experiencing when revs were low at idle.

Sorry to hi-jack your post, but I wouldn't mind getting the fuelling checked, Powerfiat are way over in basildon and I don't know of any RR"d near me — Im based in Twickenham.

Cheers
Scott

Also for any work you have DTR in mortlake, although you can't really beat Rog <img src="/forum/images/graemlins/smile.gif" alt="" />

depends how hard you are really. Rog could probably handle himself though if it came down to it. Got a lot of tools/parts to grab and swing also, so there's that element of danger you'd have to overcome.

so standard over boost is 0.2 bar and with the gtec its 1.4 and normal boost with the chip is 1.2

so my car last week had an over boost of 1.6 bar <img src="/forum/images/graemlins/shocked.gif" alt="" /> must be with the warm weather <img src="/forum/images/graemlins/confused.gif" alt="" /> (prv on its way)
but usally it overboost to 1.4 and then stays at 1.2

also i get full boost (1.2) in 1st and 2nd gear
does this mean that my car will be running a chip??

sorry to hijack <img src="/forum/images/graemlins/grin.gif" alt="" />

yep i think it does i mean im running a standered chip and in 1st and 2nd i get 0.9 bar max i think the standered chip is menta be limited to 0.8 i hope i dont have a chip i think mines just a little over boost not sure tho but if your getting 1.2 bar in 1st n second more than likely it has been chipped

Can I just fit a chip on its own? Answer yes but you shouldn't <img src="/forum/images/graemlins/wink.gif" alt="" />.

thanks allystew,thats all I needed! lol
