Paul,

I wouldn't call 200 more rpms at idle a horrible side effect. If you car was an anutomatic then it could create some problems but since it's manual it shouldn't be that detrimental.

I live in London, where it is possible to sit in near stationary traffic for 20 or 30 mins at a time, it really felt wrong to have such a high idle. Also, probably more importantly, there is less engine breaking when you have a high idle, which I really didn't like either. Finally, there is greater potential for overheating when running with a high idle (though admittedly it rarely gets hot enough here for that to be a major issue).

I do get much more "valve chatter"?? when accerating hard from very low revs with this chipset, I thought this might be pinking, but the Spanner detected not one single knock despite trying to provoke it with high load and low revs. Occurs from about 800 to 1100 rpm - Any idea what this might be?

Damn! After reading this, I might have to call for an Amityville Fatiwah on AA chips and a Xpipe!

So with my euro rated at 310 hp. I'd go up to 360 hp with a pipe and chips?

Drewster,
Last spring the local group had a tech session and we did some chip testing. Both cars were S4 manuals and with stock chips they ran virtually identically. With the performance chip installed in my car I would beat the other car by about a car length on 30 to 60 mphs test runs. The down side is the idle goes up at 1000-1150. Not a problem if you are "fun driving" the car but in stop and go, rush hour traffic it is annoying. I drive my car to work every nice day so I am putting a set of stock chips back in. If you are interested in my Autoauthority chip set send me a PM.

Ralph thanks for the offer but at this time.....Im undecided.

Red - promax offers chips sets for our S2's. Ill send you the link - via email. I dunno if they offer any substantial gains for the cost.

Peace

I'm not sure if the Euro S2s will get the same gain as the '85-'86 US 32V-ers do. The early US 32V engines seems to get the most benefit of a chip change.

AA doesn't make S2 chips. The only S2 chips I've seen for sale are the Promax(?) in the UK.Exhaust will make a big difference. Does your car have stock Euro dual exhaust?

Interesting. Sounds like I have the same chips Paul refers to, but no idle change issue. My wife didn't notice a diff from the stock chips at idle, but thought it was much more zippy in throtle response. No pinging, but I only run <recommended> premium fuel anyway. My $.02.

Paul's car is an S4 and it seems that non of the '85-'86 32Vs had any problems with detonation or idleing after a chip change.

I'm with Imo on this one....NO idle change or pinging (I've always only used unleaded Premium @ 93 RON) in my car, as outlined in the Owners manual. Its NOT "suggested"...it clearly states "Premium Unleaded Fuel" is a requirement. Even More so...if you use the chipset. Make sure the "low Octane fuel" jumper by the LH module...is NOT connected, for the optimal timing curve. The Autothority chips are definitely a step in the right direction for performance tuning of my 32V 1986.5 US car.

IMO, on my 85 the chips, exhaust and raising the stall for the torque converter gave the best $$ for the buck... after that it's a whole different game...

but you do have options: there are lots of neat "bolt on" items from devek, 928 SP, 928motorsport, 928 intl, and a few others - do a rennlist search on performance, SC, turbo or stroker (or ck my sharkpage for some links and be sure to ck out tony's and sterlings sharkpages too)...

like everything, it$ ju$t a matter of how fa$t you want to go it's just a 302cu motor (5.0 anyway) in a 3500lb car (if you discount the looks and feel). but guys like mark k. and steve pappin have managed over 335rwhp NA w/only chips, xpipe, exhaust and intake tweaks - after that, the ante goes up fast...

IMO, unless your shark is trashed, forget the 20hp airfilter, sparkplug or tuneup gains - they only exist on poorly maintained/poorly repaired cars (not that they don't exist - but just not here/rennlister's cars) dr p just didn't leave a lot on the table (unlike many OEMs of that era). so for the big numbers you'll have to pony up for blowers, bigger slugs/ cranks /valves /cams/ etc - the usual stuff everyone does for more go... just not as off the shelf or cheap as a cheby or ferd - but you do get that nice pcar crest

Thanks for all the replies - I guess I'm just going to go with Exhaust for now. The chip doesn't sound like it'll have the best Gaines for the buck, for my MY, and with all this talk of x-pipes/crossovers - it seems the best bet would be to go with the exhaust mods first.

This is what I had in mind then. Crossover w/out bypassing the cats, pull the resonators and replace them with 2 - 3 chamber flow-masters (if they will fit) then a rmb . Should be nice combination and not too loud.

Afterwards - Then maybe the suspension and brakes.
