Live Dyno tuning is allways the best, but if you want to get real close you can send me datalogs to tune off of or if you sold in a moates.net g2 and buy a burn2 using a newer flash based eeprom I'm willing to work a deal to make changes to your tune and email it for you to burn.

Do you have any maps preset for an L98/Vortec heads/SDPC intake/LT4 Cam ? In the middle of this swap, and I figured programming would be my stumbling block

Sorry, I have worked up a good timing table for the l31 heads but have only worked with the lt4 hot cam with speed density. I would be more than happy to work with you off data logs.

I have a 85 L98 4+3, Edelbrock RPM heads, Comp XE262H14 flat tappet, 1.6 rockers, Hi-Flo manifold, fully siamesed stock runners, 52mm throttle body and 24 pound Bosch 3's. My 870 ECM already has the adapter. Datalogging sucks. Doable? quote?

If you can send my datalogs with tuner pro I can assist with the tuning. I'm not a real fan of the 1f 870 slow baud.

Re: Tpi , Tbi reprograming and memcals/proms
I need to update my flyer, I like to start with the closest calibration first change injector size if needed, disable malfunction codes if needed and emissions if desired for $65 . Then based off a datalog emailed to me for $40 each additional tune I will fine tune. If anyone wants to work with me and have me do the tuning and they burn the calibration I'm willing to work out a deal there too. It depends on how much time is involved but I'm very fair in pricing

Re: Tpi , Tbi reprograming and memcals/proms
I have a 91 Z28 L98,converted to 5 speed by previous owner runs rich with a slight idle problem, it currently has a small comp cam , headers , bbk twin 50 or 54 mm tb, air pump removed , cats removed. The car runs strong but i can tell somethings holding it back. It also has a slight stumble on acceleration. In the future i would like to upgrade injectors,fuel pump and maybe ported upper and siamesed runners. Should i try to reprogram now? or wait as i do drive this car about twice a week cause its fun!

Re: Tpi , Tbi reprograming and memcals/proms
I had him reprogram a prom for my 1988 Formula 350 with some minor performance twinks and the 9th injector delete. Very happy with the results, fast turn around. If you want some ECM tuning done, I highly recommend him.

Re: Tpi , Tbi reprograming and memcals/proms
I think the best thing to do is to figure out if it is the injectors causing the stumble, tps, cts, bad map or dead or lazy o2. If it has the factory multec injectors start there and give southbay a call and get some bosch 3 22#hr injectors. getting tuner pro rt and a aldl to USB cable is a real valuable tool. Feel free to send me a pm and I will be more than happy to try to help you figure out what's going on and get your engine to run better

The only issues I have I have seen with a automatic tune with a manual transmission is slight bucking on deceleration.
