How to increase RWHP?
mod(s) should I do next to increase power? Current mods are listed in sig.
Why would you expect a 99 (LS1 intake), Automatic would do 300. The intake if you do all of it is worth 13-14 rwhp on a 6 speed, I know because I just did it, there is a new book out by SA design which has like over 100 engine dyno combos, Ported TB gain, but not that much. Catbacks do like 4-8rwhp, Hypertech helps but its marginal at best.
The big thing in to see if what you dyno is you need to lock the converter, to get a true reading, a fluid coupling in the driveline isnt very accurate. Not to say the car cant run a good time, there are tons of big cube, high stall , th400 guys beating the hp/et calculators left in right by a large amount.
