Over the past summer I swapped a 3800 from a 1998 Grand Prix GTP into my 1988 Fiero keeping the 4T65e-HD transmission. I am just now getting around to having the PCM tuned.

I am turning to Pennock Forums to ask if I should have a "Fiero" flash installed by ZZPerformance? If not, what route should I take / who will be willing to program my PCM before the end of the month? I am looking for a 2 week turnaround. The engine has all emission control units in tact (sans rear O2 sensor) and a 180* T-stat installed.

I live right outside of Philadelphia, PA so if anybody nearby has a Dyno so we can do a proper adjustment in the car, that would be fantastic. Please let me know. I appreciate any and all help. Thank you very much.

I think you should send Nosrac on here a PM and have him flash your PCM for the Fiero......He will do it cheaper that ZZP I am sure.....

PM sent. Thanks for the help.

Ryan at Sinister Performance is also able to supply you with a tune.

I agree on Ryan he does a nice tune as far as you can get with out having an in car tune.
Some harness builders like myself also supply programmed PCM's matched to the harness at no extra cost when purchasing a harness.
Of course this does not help you but others reading this post might find it use full. Dan

Based on price, it looks like Nosrac is cheaper. Can anybody who has experience with both try to point me in the right direction? I am not building a track car, nor a daily driver. More of a weekend cruiser that I will beat on from time to time. Engine is in mostly stock condition; however, entire top-end has been rebuilt.

Thanks for the help!

While forum members mentioned can provide good 3800SC tunes; if you do any mods to your engine it will require testing, retesting, continual scanning and tweaks to the program. Mail order tunes can get you started, running, provide a tune in the general area but rarely are they optimal.

I have been using Nosrac for a while since the other local guy I used dropped out of the game..You are going to get basically the same tune from anyone you choose to go with. I can vouch for Nosrac as I am currently running his tune and have been for some time.....I have used a PCM tuned by Darth also as it came with a almost complete swap that I bought...Like I said either will be pretty much the same....

Thanks for everybody's help! I now have a much better direction than I did yesterday which is why I came to Pennock in the first place!

It is best not to swap PCMs but instead have yours reprogrammed. If you swap PCMs you may end up needing a Case Learn procedure.

Also if your programmer is not asking how your engine is set up, and what power modifications you have made, you know your programmer is giving you a very generic tune.

If you get a "performace" tune then you need something to scan for KR. I haev an aeroforce scan guage in my car but it can't export data.

I have a "scanmaster" that I stole from DH. It doesn't log anything but it shows me all the engine parameters including knock. I haven't seen any kr readings since I went to E85 though

Ryan at Sinister Performance for tune and phonedawgz for harness. Car started at first crank and 5 days later it was at RFTHs with no issues. AFR and KR looks great for a first time mail order tune. These guys know what they do and ask the right questions.

For the record after tuning just about every combination of 3800 you could possibly think of, many times over, this could not be further from the truth.

If you need to "tune" stuff, you have mechanical problems you are trying to fix.

Thanks for the endorsement! I strive to be the best.

True...to a point as tunes from the factory are conservative and there are a lot of gains to be had in a mail order tune. Optimal no...much better YES.
If you are referring to AFR MAF tuning then you are correct about the continual scanning and tweaking. However, AFR from the factory is NOT spot on due to different geographic areas, altitudes, avg temp differences, engine variances, etc. Hell, some factory cars come stock with up to 5* of KR @ WOT. In car tunes are better but mail order works well too, as there are many areas to improve on the stock tunes.
