You can't pull codes correctly on a modified tune since no telling what the tuner disabled. Stock tune would be upset with long tubes since the o2's are farther back. There could be any number of reasons why it wont set it. Most common is that the tuner disabled the rear o2s, disabled the...

if you work at a performance dealership yall should have access to reading and writing tools. If so, LMK and I can shoot you a file to get you started.

hptuners probably doesnt have access to alot of the etc parameters youll want cib is closed in bore

How safe it is will depend on how much timing you have in her. But yeah fuel wise shouldnt be a problem.

713 is what a stocker makes at 15s on e85 cams, ported heads and 2 more lbs of boost id expect somewhere around ~850rwhp depending significantly on how well they ported the heads. Why not kick her up to 24lbs ?

yeah you can't just swap throttle bodies without letting the ecu know

divide all the CIB parameters by 8 /done

Anyone can tune with a quarterhorse the software tunerpro is free. you plug the qh in to the ecu, read the ecu, then load a stock compare file and click compare differences if more than just the pats code and vin is different then its not a stock file and has been modified and will is not...

Anytime you've ever flashed a tune to your ecu and then return it to stock you need to verify its fully returned to a stock production cal. The only way to verify is to use a moates quarterhorse to read the current tune off the ecu and verify it against a stock production cal to make sure only...

If tuned properly then it would be perfect fine. however, they probably turned off the rear o2s and if tuned using a flash device that changes the stock tune you'd fail regardless.

Its not bad just get it all nice and hot first and it should come out easy. yes fouled o2s will dump fuel in the fuel trims, in closed loop the o2s control fuel. At 50k miles you can see o2s start to shift and begin reading skewed.

fill it with the engine running might help to diagnose any eec iv or eec v you need a moates quarterhorse. Use the fuel error over rpm and airmass to see if its your maf or injectors that are acting up. your a little past 50k miles on them o2s. definitely time to change them.
